Methods to Save Net Accessibility from Itself – A Record Aside

As is now fairly broadly identified amongst indie builders and just about
unknown in all places else, web sites are correctly created in accordance
with revealed accessibility requirements. The chief supply for these
requirements is the set of “suggestions” by the World Huge Net
Consortium’s Net Accessibility Initiative (the W3C WAI). These Net Content material Accessibility Tips (WCAG 1.0)
have been final formally up to date in 1999.

Article Continues Beneath

A brand new revision of the rules, WCAG 2.0, is being written. The
improvement course of goes slowly and is at risk of
recapitulating most of the errors of WCAG 1.0 — unrealistic
tips divorced from real-world internet improvement which can be without delay
too obscure and too particular.

However you, the indie developer, will help forestall this tragedy by
investing a small time frame in a single of some restricted areas that
might curiosity you. As an alternative of engaged on your complete WCAG, we want you
to deal with subjects through which you’ll have experience or expertise. By
collaborating on this restricted approach, you’ll be able to assist save internet
accessibility from itself.

Enlightened self-interest#section2

If you happen to select to make standards-compliant web sites, inevitably you
should comply with the rules. It’s foreseeable that you simply
may very well be legally required to comply with WCAG 2.0. You may decide into
following the rules or they may very well be foisted upon you.

You thus have an enlightened self-interest in making certain the brand new
tips truly make sense. Furthermore, we merely want extra
contributors.

The participation downside#section3

I’ve been posting to the W3C’s accessibility-related
mailing lists since 1999 and I nonetheless
haven’t discovered how the WAI works. You don’t have to,
both.

You simply have to know that the 2 principal mailing lists for WAI discussions are:

WAI-IG: WAI Curiosity Group. Basic dialogue of internet
accessibility.
WAI-GL: WAI Tips, dwelling of the Net
Content material Accessibility Tips Working Group. Dialogue of
present and future tips.

Not surprisingly, extra individuals are eager about WAI-IG’s
common chitchat than WAI-GL’s topic-specific discussions. From
June 2002 to June 2003, 290 totally different folks posted to WAI-IG, however
fewer than half as many (114) posted to WAI-GL.

That appears like loads, nevertheless it isn’t. Net improvement now
ranges broadly, with many overlapping fields of experience. WCAG 2.0
will impinge on a lot of these fields, together with web page construction (XHTML
and related markup languages), CSS, multimedia, usability,
data structure, writing, and myriad disability-specific
points. I do know for a indisputable fact that main consultants in a number of internet subjects
unrelated to incapacity, whose names can be instantly acknowledged
by au courant indie builders, merely don’t
put up to both mailing listing. We have now no proof that precise consultants
in lots of pertinent fields are a part of the event course of for WCAG
2.0.

And it reveals. The present drafts of WCAG 2.0 are a marked and
indeniable enchancment over the antediluvian WCAG 1.0, however they
nonetheless have far too little bearing on the true world of the net.

That is the place you are available in.

At press time, the present draft of WCAG 2.0 was 14,000 phrases lengthy
with out markup. I don’t see how anyone may sort out one thing
that large in a single sitting. It’s like an anaconda making an attempt to
swallow a Vary Rover.

What I’ve accomplished, then, is to interrupt up the WCAG draft into
“motion objects,” because the enterprise varieties say. The themes I
have chosen are:

Rewrite: The rule
wants rewriting and clarification
Examples: The rule
requires many extra examples, ideally drawn from precise web sites
(anonymized if mandatory)
Unclear on the
idea: There’s one thing unsuitable with the essential
concept of the rule
Unimaginable: The rule, as written, is
unimaginable to satisfy or just about so
Not our
downside: The situation can’t moderately be solved
by tips governing internet content material

Earlier than everybody begins accusing me of being “too
crucial,” which is like accusing the sky of being too blue,
perceive that this text is a deficiency report on WCAG
2.0. We are able to’t afford to fake to be extra optimistic, upbeat,
and complimentary than is justified by the precise tips. We have now
solely a brief window of alternative to repair what’s unsuitable, and we
can’t try this with out figuring out what’s unsuitable. This
is not any time to intensify the optimistic.

The method right here is just like engineering documentation, the place
succeeding drafts produce deficiency experiences, every of whose objects is
both corrected, dominated to not be a deficiency, or just lived with
till the following draft. The method recurs till collaborators have
corrected or determined to stay with each error.

(I’ve individually written two briefing paperwork for a earlier
face-to-face WCAG assembly that listing deficiencies and suggestions, if anybody is .)

The place to seek out the originals#section6

WCAG 2.0 is a shifting goal.

The paperwork don’t use sufficient fragment identifiers. You
can’t hyperlink on to sufficient sections and paragraphs. The place
there’s a hyperlink, I’ll give it, however a variety of the time
you’re going to be caught utilizing the Discover command in your
browser. Furthermore, in subsequent drafts, wording is assured to
change.

Rewrite#section8

These tips want rewriting and clarification. However the issue is
a lot worse than that: The entirety of WCAG 2.0 is a
poorly-written morass. The doc violates its personal draft tips
on clear and easy writing. It’s an outright mess, and pressing
plain-English rewrites are required. The Net Accessibility
Initiative, which has a funds, ought to rent skilled
plain-English consultants for this process. It’s time to finish the
W3C’s custom of incomprehensible paperwork.

Nonetheless, for the needs of this part, we’ll deal with
sections that make subsequent to no sense as written.

Overview of Design Rules: Right here, the 4 themes or
“targets” of WCAG 2.0 are considerably clumsily named as
adjectives.

<blockquote

- Perceivable
- Operable
- Comprehensible
- Sturdy
Make content material perceivable by any person. The checkpoint wants fixing. May you implement it
as written?
All non-text content material that may be expressed in phrases has a textual content
equal of the operate or data that the non-text content material
was meant to convey.
1. Non-text content material that can be expressed in
  phrases has a textual content equal explicitly related to it.
2. Non-text content material that can’t be expressed
  in phrases has a descriptive label offered as its textual content equal.
3. The textual content equal ought to fulfill the
  identical operate because the creator meant for the non-text content material (i.e.,
  it presents all the meant data and/or achieves the identical
  operate of the non-text content material).
What is “non-text content material”?

Non-text content material consists of however just isn’t
restricted to pictures, textual content in raster photographs, picture map areas,
animations (e.g., animated GIFs), ASCII artwork, photographs used as listing
bullets, spacers, graphical buttons, sounds (performed with or with out
person interplay), stand-alone audio information, audio tracks of video,
and video….
WAI’s warning in opposition to using illustrations: If this
guideline even deserves to be included, it requires rewording.

Designers have to be cautious in deciding when to make use of
illustrations. Studying an image might be a realized exercise that
is simpler for some than others. Some customers skip the photographs; others
learn solely the photographs. Designers should additionally acknowledge that visible
conventions usually are not common and that people develop their very own
psychological schema and expectations in deciphering visible data.
Retransmitted captioning and audio description: Are you able to perceive
this guideline?

If content material is rebroadcast from one other medium or
useful resource that complies to broadcast necessities for accessibility
(impartial of those tips), the rebroadcast satisfies the
checkpoint if it complies with the opposite tips.
Definitions must be definitive. These
aren’t.

content material

Content material is the data or
that means and performance.

presentation

Presentation is the rendering of
the content material and construction in a type that may be sensed by the person.

construction

Construction consists of each
hierarchical construction of the content material and non-hierarchical
relationships comparable to cross-references, or the correspondence between
header and knowledge cells in a desk.

Examples#section9

On this part, these tips require extra examples. Right here is
the place my readers can do essentially the most good with the least effort: All we
want, in most of those sections, are a number of folks’s
contributions of 1 or two examples every of real-world websites. The
websites you recommend may totally meet, partially meet, or fully fail
the proposed guideline.

You may also recount your individual lived experiences as an internet person.

The vital factor right here is to get WAI out of its behavior of
half-arsed hypothesizing. We would like their tips utilized in opposition to
current websites of all descriptions. WAI just isn’t eager about discovering
these websites by itself, so now we have at hand the information to them on a
platter.

But
extra textual content equivalents. WAI simply can’t get sufficient of these.
However we want a wider vary of precise examples of textual content equivalents in
actual use right now, whether or not well-done or not.
1. Non-text content material that can be expressed in
  phrases has a textual content equal explicitly related to it.
2. Non-text content material that can’t be expressed
  in phrases has a descriptive label offered as its textual content equal.
  - The textual content equal ought to fulfill the
    identical operate because the creator meant for the non-text content material (i.e.,
    it presents all the meant data and/or achieves the identical
    operate of the non-text content material).
WAI dabbles dangerously within the situation of writing, a subject about which
it has a demonstrable lack of awareness. Its concern
with “concrete ideas” and related classifications of
the written phrase is supposed to help folks with studying
disabilities, however little good will come of it until we all know precisely
what they’re speaking about. Do you?
- Instance 1: An outline of a
  course of.
  
  A web page describes the best way to study to play soccer. Every
  step in studying the basics of the sport is illustrated with a
  {photograph} of a participant doing what’s described within the textual content.
- Instance 2: A concrete
  idea.
  
  The first idea on a web page is concrete. It’s
  discussing Mt. Pinatubo. It consists of each an outline of the 1991
  eruption in addition to pictures of the eruption and the aftermath. It
  hyperlinks to a different web site that incorporates video and one other web site that
  incorporates a 3D simulation of what occurred beneath the crust and
  inside the volcano throughout the eruption.
- Instance 3: Youngster’s report of college journey.
  
  A baby went along with her faculty on a visit to a
  bicycle manufacturing plant. She wrote a report for her household and
  pals to put up to the net. Within the report, she consists of the corporate
  brand in addition to an image of a bicycle on the meeting line. She
  hyperlinks to the corporate web site for extra data. She consists of
  pictures she took of the plant.
- Instance 4: Inventory-trading
  knowledge.
  
  A information web site is evaluating the efficiency of the
  economic system from third quarter of this 12 months with third quarter from the
  final three years. They evaluate costs of the most well-liked shares.
  They current the information in a bar graph with a hyperlink to the uncooked knowledge they
  used to create the bar graph.
- Instance 5: Historical past of music.
  
  A grandfather’s pastime is listening to and
  taking part in music. He creates a web site that features examples of many
  various kinds of music and musical devices. When describing
  particular sorts of music, he hyperlinks to a brief sound clip.
Advantages
of accessible alternate options want a number of case research (which, oddly, WAI
may crib from its personal web page).
- People who’re blind, have low imaginative and prescient, have
  cognitive disabilities or have hassle studying textual content for any motive
  can have the textual content learn aloud to them.
- People who’re deaf, are arduous of listening to or
  who’re having hassle understanding the audio data for any
  motive can learn the textual content presentation or have it translated and
  introduced as signal language by their assistive expertise.
- People who’re blind or deaf-blind can have
  the data introduced in Braille.
Examples
of multimedia accessibility: I do know I’m not the one one
who truly watches captioning and audio description. I do know that
few concerned in WAI do. Actual-life experiences and examples are referred to as
for right here.
- Instance 1: A film clip with audio
  description and captions.
  
  A clip from a film is revealed on a web site. In
  the clip, a toddler is making an attempt to lure a pet to the kid’s
  bed room by laying a path of crumbs. The kid mumbles inaudibly to
  himself as he lays the path. When not watching the video, it isn’t
  apparent that he’s laying a path of crumbs since all you hear is the
  mumbling. The audio description that’s interspersed with the
  baby’s mumbling says “Charlie lays a crumb on every stair
  resulting in his room.” The caption that seems as he mumbles is
  [inaudible mumbling].
- Instance 2: A video clip of a information
  story.
  
  A video clip accompanies a information story concerning the
  latest flooding in a significant metropolis. The reporter describes what’s seen,
  for everybody. No audio description is critical. The captions show
  what the reporter is saying.
- Instance 3: A silent
  animation.
  
  An animation reveals a pantomime climbing a ladder.
  There isn’t a audio observe for this animation. No captions or audio
  description are required. As an alternative, a textual content equal is
  offered….
Absolutely we are able to give you higher real-world examples of a second
language embedded in a paragraph. I additionally cleaned up WAI’s copy
errors beneath.

Facilitating unambiguous decoding of characters and phrases
in content material can also be useful for people who’re studying to learn
or studying a second language….

Within the following sentence, “And with
a sure je ne sais quoi, she entered each
the room, and his life, endlessly,” the French phrase je ne sais quoi is marked as French. Relying on
the markup language, English might both be marked because the language for
your complete doc besides the place specified, or marked on the
paragraph stage.
The WAI is unaware that right desk markup makes desk construction
crystal-clear. Additionally, precisely what “semantic markup” may
make, for instance, homonyms, homographs, and figures of speech
comprehensible?

Present a abstract for relationships that might not be apparent from
analyzing the construction of a desk however that could be obvious in a
visible rendering of the desk.

If
contracted types of phrases are used such that they’re ambiguous,
present semantic markup to make phrases distinctive and interpretable.
Right here
is the place standardistas shine. We’re obsessed with the
correct use of lists, headings, and different XHTML components. Time to offer
WAI a style of our wonderful compliant medication. We might have an issue
discovering examples of “chapters” and
“sections,” as a result of, though they’re outlined as
“relationships” of the hyperlink
aspect, there are not any HTML components for chapters or sections.

(This passage of the WCAG is especially pathetic, resorting to
citing the construction of a bicycle to elucidate internet construction.)
1. The content material has been reviewed, taking into trương mục the
  following methods for facilitating orientation and motion,
  making use of them as acceptable.
  1. Breaking apart textual content into logical
    paragraphs
  2. Offering hierarchical sections and
    titles, significantly for longer paperwork
  3. Revealing vital non-hierarchical
    relationships, comparable to cross-references, or the correspondence
    between header and knowledge cells in a desk, in order that they’re
    represented unambiguously within the markup or knowledge mannequin
  4. Dividing very massive works into sections
    and or chapters with logical labels
  5. Others?
What number of “increasing outlines” and “dynamic fisheye
views” have you run by the W3C validator recently?
web site navigation
mechanism
A web site
navigation mechanism is a mechanism for simply orienting and
shifting about inside the web site. Web site navigation mechanisms embody however
usually are not restricted to:

A
dwelling web page with hyperlinks on it and subsequent pages that hyperlink to the
different pages on the web site

Web site map(s)

Search engine(s)

Increasing define(s)

Dynamic fisheye views displaying all linked pages or subjects
associated to any web page.

3D
digital representations of web site content material
Higher examples of constant
web site format, anybody?

Unclear on the idea#section10

These tips present such a deep misunderstanding of the subject they
fake to sort out that they need to be deleted or massively rewritten.
The place you’ll be able to assist: See in the event you can determine what they’re meant
to imply and rewrite them. Or recommend causes, ideally backed up
with references to real-world websites and improvement practices, why
they need to be deleted.

Does anybody, in any respect, anyplace, use blinking textual content anymore, and if that’s the case,
what number of of these individuals are utilizing “client-side
scripting” to do it reasonably than merely utilizing blink or <a href="http://www.w3.org/WAI/UA/TS/html401/cp0303/0303-CSS-BLINK.html" id="text-decoration-blink" title="text-decoration:blink within the fashion aspect">text-decoration:blink? What number of person stylesheets
can override scripts?

Shopper-side scripting is used to create blinking
textual content. The person can deactivate using scripting in his or her
browser or override using scripts with a person fashion sheet.
Unicode
encoding is fascinating, however it isn’t the one encoding obtainable,
nor does its absence impair accessibility.

Textual content within the content material is offered in Unicode or enough
data is offered in order that it may be robotically mapped again
to Unicode.
This guideline issues captioning of internet multimedia. Its plain
studying requires a transcript of all real-time audio broadcasts. That
is, each single Web radio station would require transcription.

In the meantime, you probably have any sort of webcam in any respect, it is advisable
scrounge up another web site you’ll be able to hyperlink to that’s by some means the
“equal” of the webcam’s picture.

If the net content material is real-time and audio-only and never
time-sensitive and never interactive a transcript or different non-audio
equal is enough. […]

If the net content material is real-time non-interactive video (e.g., a
webcam of ambient circumstances), both present an equal… (e.g.,
an ongoing replace of climate circumstances) or hyperlink to an equal…
(e.g., a hyperlink to a climate web site).
The Net Accessibility Initiative misunderstands using cascading
stylesheets. Right here
it requires you to give you a unique look for dozens of
HTML components. (Ought to the weather em,
cite, and i actually look totally different?) It additionally
requires you to code particular black-and-white and monaural stylesheets.
The structural components current have a unique visible
look or auditory attribute from one another and from physique
textual content. […]

The structural emphases are chosen to be distinct on totally different
main visible show varieties (e.g. black and white, small show, mono
audio playback). […]
1. For visible displays, use font variations, kinds,
  dimension and white area to emphasise construction.
2. Use colour and graphics to emphasise construction.
3. For auditory displays, use totally different voice
  traits and/sounds for main headings, sections and different
  structural components.
4. If content material is focused for a particular person group and the
  presentation of the structured content material just isn’t salient sufficient to satisfy
  the wants of your viewers, use further graphics, colours, sounds,
  and different elements of presentation to emphasise the construction.
Foreground/background
distinctions are, as they are saying, a private factor. WAI has offered
no proof that authors can moderately anticipate how an individual with
a visible impairment or studying incapacity might be confused by
determine–floor mixtures. Additional, who runs in “256
grayscale” anymore, not to mention black and white (i.e., one-bit
color, like the unique Macintosh)?
1. When textual content content material is introduced over a background picture or
  sample, the textual content is well readable when the web page is considered in 256
  grayscale.
2. Textual content content material just isn’t introduced over a background picture or
  sample or the textual content is well readable when the web page is
  considered in black and white (no grayscale).
3. Audio content material doesn’t comprise background sounds
  or the background sounds are no less than 20 db decrease than the
  foreground audio content material.
4. Textual content content material just isn’t introduced over a background picture or
  colour or the colours used for the textual content and background or
  background picture move the next take a look at:
WAI has not acknowledged that many, and even most, web-based video games are
going to be inaccessible to somebody. It doesn’t make a variety of
sense to warn of an unpredictable response, thus making it
predictable.

The place inconsistent or unpredictable responses are important to the
operate of the content material (e.g. thriller video games, journey video games, assessments,
and so on.) the person is warned upfront of encountering them.
Right here is the only largest minefield through which the Net Accessibility
Initiative finds itself: Writing tips for learning-disabled folks,
who, the WAI is unable to acknowledge, might by no means be considerably accommodated on-line.

The present drafts are an enormous enchancment over earlier strategies,
however WAI nonetheless clings to the notion that “content material” may be
“reviewed” to exhibit that it’s as merely written as
doable. However write too merely and it’s possible you’ll alienate your goal
viewers. Right here accessibility turns from making websites accessible to
rewriting your individual work — and making you illustrate it.
Content material is written to be no extra advanced than is critical
and/or complement[ed] with easier types of the content material.
- the content material has been reviewed, taking into trương mục the
  following methods for evaluating the complexity of the content material,
  making use of them as acceptable.
  1. Familiarity of phrases and language
    construction
  2. Reasonableness of size and complexity of
    sentences
  3. Coherence of paragraphs (and sensibility
    in size)
  4. Readability of headings and linked textual content when
    learn out of context
  5. Accuracy and uniqueness of web page titles
  6. Care in using all-capital letters
    the place regular sentence case may improve comprehension
  7. Inclusion of non-text content material to
    complement textual content for key pages or sections of the location the place they felt
    it was acceptable.
Backward
compatibility. There’s solely up to now again we are able to go in a
world the place almost everybody makes use of a Model 5–or-later browser
and authors are writing legitimate HTML and CSS, that are themselves
speculated to be appropriate throughout browsers and units.

As ever, there’s a lot dialogue of individuals with outdated
expertise, which is an accessibility situation in a way apart from
these inside WAI’s purview. Everyone else has to improve; why
are folks with disabilities exempt? Ought to standards-compliant
progress on the net be hindered as a result of somebody someplace is perhaps
utilizing an previous display reader?

Neither is there any understanding of the brand new and extra priceless idea
of progressive enhancement — utilizing
baseline HTML and CSS to be appropriate with any compliant gadget, however
including options that more-sophisticated units can use.
Advantages of figuring out and documenting baseline person agent
necessities:
- People can establish (both by web site
  documentation or robotically by metadata) whether or not or not they
  are doubtless to have the ability to use a web site. At the side of a search
  engine or a proxy server, this may very well be used to robotically filter
  out websites a person can’t entry or to robotically filter to the highest
  websites that may be most usable.
- Requiring websites to doc their baseline will
  trigger them to guage assumptions about person brokers and can
  decrease the variety of websites which can be inadvertently inaccessible
  as a result of they’re unaware of backward compatibility points.
Advantages of designing for backward
compatibility:
- People who should use different searching
  applied sciences and units will be capable to entry the content material.
- People who can’t afford or in any other case don’t
  have entry to newer applied sciences additionally profit from backward
  compatibility in that they won’t have to buy upgrades or
  tools as usually.

Subsequent to unimaginable#section11

The Net Accessibility Initiative publishes the next draft
tips despite the fact that they’re truly or almost unimaginable to
implement. Right here we want you to supply technical explanations, which
WAI members ought to have been in a position to give you themselves however have
not. Or you possibly can nominate examples from the true world and discover
how tough it might be to use the rules to them.

“Collating” a “script” of audio descriptions
and captions has been accomplished precisely as soon as in recorded reminiscence —
for an indication challenge that’s not documented on-line. It’s
unimaginable in observe because of the lack of interchange codecs for
captioning, audio description, and associated fields. Nor are there that
many examples of multimedia which can be captioned and
described. It’s even uncommon, when you think about the total vary of
TV applications and flicks, to seek out each captioning and outline in
these well-established fields.

Dwell captioning is awfully tough for on-line media (almost
unimaginable utilizing standards-compliant code), whereas stay description
has been tried a mere 5 instances within the broadcast sphere.
In the meantime, after all captions require you to learn and watch
on the identical time. This isn’t telepathy.
1. a textual content doc that merges all audio descriptions and
  captions right into a collated script (that gives dialog, vital
  sounds and vital visible data in a single textual content doc) is
  offered.
2. captions and audio descriptions are offered for all stay
  broadcasts which give the identical data.
3. the presentation doesn’t require the person to learn
  captions and the visible presentation concurrently so as to
  perceive the content material.
It’s unimaginable to put in writing a stylesheet that detects
the dimensions and color capabilities of a show and serves
totally different instructions consequently. Nearly no person makes use of black-and-white
shows; audio stylesheets are successfully unsupported, and stereo
audio is the norm. The rule additionally apparently requires
stylesheet-switchers on each web site. The idea of
“differ[ing] the emphasis of the construction” is reasonably arduous
to know, until it means making sure components invisible or
but different components render in 96-point kind.
1. The structural emphases are chosen to be distinct on
  totally different main visible show varieties (e.g. black and white, small
  show, mono audio playback).
2. Content material is constructed such that customers can management the
  presentation of the structural components.
3. Alternate presentation codecs can be found to differ the
  emphasis of the construction.
This guideline,
meant to assist dyslexics and others with associated studying
disabilities, presupposes a Home windows-style combo field (drop-down listing
plus type-in discipline). It might additionally require you to spell-check each
enter ever made in your web site. That might appear to be the
customer’s accountability, and it’s already
doable.
1. The place doable, the person is allowed to pick out from a listing
  of choices in addition to to generate enter textual content straight.
2. Errors are recognized particularly and strategies for
  correction are offered the place doable.
3. Checks for misspelled phrases are utilized and proper
  spellings are steered when textual content entry is required.

Not our downside#section12

The Net Accessibility Initiative’s Net Content material
Accessibility Tips are meant “to make internet content material
accessible to folks with disabilities.” But these proposed
tips for WCAG 2.0 lengthen effectively past internet content material into unrelated
technical fields and, certainly, the thoughts of the creator.

Right here your contribution may be an skilled opinion on how the proposed
guideline would apply to your web site. Would you fail, move, or fall
someplace in between? Wouldn’t it even be doable so that you can assess
whether or not or not you comply? How would a Net Content material
Accessibility Guideline comparable to this have an effect on your internet improvement?

Would you like the Net Accessibility Initiative dictating to you ways
“advanced” or “unfamiliar” your content material may
be, and even whether or not it is perhaps advanced in any respect? If utilizing knowledge tables,
received’t you already be utilizing right desk markup?
Content material is taken into account advanced if the
relationships between items of data usually are not simple to determine
out. If the presentation of the data is meant to spotlight
tendencies or relationships between ideas, these must be explicitly
acknowledged within the abstract.

Examples of advanced data:
- Knowledge tables,
- Ideas which can be esoteric or
  obscure,
- Content material that includes a number of
  layers.
unfamiliar content material

Content material is perhaps unfamiliar if
you’re utilizing phrases particular to a specific group.
Abbreviations
and acronyms are an issue which will by no means be satisfactorily
resolved, no less than not till display readers — the primary sticking
level right here — are upgraded to deal with them higher. In the meantime, the
dialogue of diacritic marks is an try to drive authors to put in writing
Arabic and Hebrew with the vowel markings which can be usually deleted
in adult-level writing — once more all as a result of display readers
can’t deal with the writing system as grownups use it.
1. Abbreviations and acronyms are clearly recognized every
  time they happen.
2. Symbols comparable to diacritic marks which can be present in normal
  utilization of the pure language of the content material, and which can be mandatory
  for unambiguous identification of phrases, are current or one other
  normal mechanism for disambiguation is offered.

You probably have something to contribute to the WCAG 2.0
improvement course of, you’ll be able to put up a message to the WAI-GL mailing
listing (wai-gl at lists.w3.org).
You’re additionally requested to put up to
one other listing, public-comments-wcag20 at w3.org.
Each lists have archives on the net (WAI-GL, ).
There’s additionally a Bugzilla implementation for
WCAG, although you’re not allowed to
“talk about” points there.
WCAG holds a number of “f2f” conferences every year; the following is in Tokyo.
I actually encourage you to publish feedback by yourself
weblogs, with hyperlinks despatched alongside to the mailing lists. That can get
the message out to extra readers, and likewise put a bit extra public
strain on the Net Accessibility Initiative to create higher
tips.
