you make a lot of really good points,
some critical needs that may have been overlooked. 
My recommendation is to continue on the line of thinking 
that "There are user agent problems", 
and to get that handful of browsers to not only get those problems fixed, 
to address some of the preceived "content author" problems.
Even though there are many problems where 
"the solution is entirely within the scope of content authors" 
I believe that with some hard work with the browser guys and gals, 
that those problems may be even easier solved with better browsers 
without external AT. 
It just seems to me to be an even more 
achievable battle or war 
to fight and join the browser guys 
than spread ourselves too thin with all the conent authors, 
there are just too many of them.

This next example doesn't solve some of the problems you mentioned,
but there are some pretty good APIs available to 
AT developers,  browser developers, and authoring tool developers
that can already send an image to a software service 
to get the text alternative on the fly.
In other words, no need to wait for the content author to make the repair
and add the alt text.

There are a few points to consider.

- The 2.1 Criteria can strengthen requirements but cannot weaken one. Thus 
to meet 2.1 you may change the level from AA to A but you cannot move from 
AA to AAA. You may also add additional requirements to an existing SC. 
Also, failure to meet 2.1 will not negate conformance to 2.0. If you want 
2.1 conformance you must do more. This was in the TF''s  and WCAG's 

- At least on the LV task forces we are focusing on content. The ability 
to restructure the presentation to a linear arrangement of elements is 
completely achievable with content. Resizing text to much more than 200% 
with word wrapping is entirely an issue of content. Here are some common 
barriers that interfere with access.

* Fixed Top Banners
* Tabular structure that causes lines of enlarged text to run off the page 
(Seen frequently in Webmail clients)
* RWD pages that prevent text enlargement
* Inline style specifications that disable cascading style sheets
* Use of background images for anything but decoration
* Multi-column format (Even worse when layout tables are used)
* Margins and padding that resize with font size
* Pages that do not allow restyling
* Use of HTML elements like <select> <option>, and input type radio that 
do not support style changes.

Content that interferes with single column reconfiguration, element level 
customization, control of line length and enlargement with word wrapping 
is inaccessible content, and it is unnecessary.

There are user agent problems. The fact that change of font size loses 
your place in the file using almost every user agent is not a problem of 
the content author. We know the difference.

- The model of external AT works well for some disabilities. It is not too 
effective for others. In the case of providing a single column interface 
that enables very large print for people with acuity reduction and short 
lines with normal print for people with peripheral field loss the solution 
is entirely within the scope of content authors.

Phil, I had no intention of saying that some criteria were not important 
to some users.  I agree they are all not just usability issues. They are 
barriers to users with disabilities.  But as you acknowledge some are 
items that must be solved by the author while others can be solved through 
the browser or AT.  The Understanding Conformance document indicates that 
levels are set based on whether the Success Criterion is essential (in 
other words, if the Success Criterion isn't met, then even assistive 
technology can't make content accessible).  So to that degree they carry a 
greater weight.
So when I used the term important I was thinking more along these lines ? 
some SC are essential because they can?t be worked around by AT and thus 
having the author address these is of greater need.  The term severity or 
priority would probably also be objectionable.  But knowing which criteria 
affect multiple user groups and which ones can?t be worked around are real 
world needs that organizations must consider when there is a limited time 
to fix issues.    Most organizations do have to prioritize issues whether 
something is a barrier versus something AT can overcome is a realistic 
factor in helping them make these decisions.    While using the term 
change level would be best?it carries an ambiguity  ? but in the email I 
was responding to it appeared that there was confusion about what level 
was the minimum level of accessibility.  Also many organizations are 
confused when we speak of Level AA conformance and automatically assume 
incorrectly that excludes level A conformance.  So we do need to find a 
term that is appropriate and understandable to communicate.  What term 
would you recommend?

Subject: RE: WCAG 2.1
I do not support of the use of phrases such as "raising" or "lowering 
importance" or making a success criterion "more" or "less important".  
There is a misunderstanding out there about the levels (or its just a 
misunderstanding in using English to describe things or me in 
understanding things).  Saying that it is important today or more 
important tomorrow to conform with the success criteria is a very 
different concept in my mind that saying that level A success criterion is 
more important to this end user than a level triple A success criterion is 
to that other user. Remember that it is the web content accessibility 
guidelines WCAG , not the end user experience guidelines.  In my opinion 
all the success criterion are important, period.  Level A and double A and 
triple A are not about importance, they are about if and when they apply 
to the web content (vs the browser or AT) and to whom do they benefit.  
One of the questions that the working group asked themselves when 
assigning a level to the success criterion was the following: Does it 
        to all the content all the time?
        to all web sites all the time?
        for all audiences all the time?
Another questions that was asked was about whether it is best solved by 
the user agent (browser and/or AT) or whether it is best solved by or in 
the web content by the web designer and developers. You can read a wide 
range of interacting issues that the working group consider in 
Understanding Levels of Conformance.

Conformance with triple AAA is not better or more accessibility, it is 
more responsibility on the author more of the time because its more 
applicability.  The notion of "higher levels" (not higher importance) of 
conformance comes from that concept that meeting triple AAA requires 
passing more, all 65 success criteria, while double AA conformance means 
passing fewer only 38 success criteria. Level A is the lowest level, 
meaning it only requires meeting 25 success criteria.  Even the normative 
WCAG standards says: 
"Conformance  This section is normative. . . . Note 2: It is not 
recommended that Level AAA conformance be required as a general policy for 
entire sites because it is not possible to satisfy all Level AAA Success 
Criteria for some content."  

Also, because of conflicts I never recommend requiring many of the Level 
AAA success criterion all the time on all web content for all users.  Here 
are 3 examples: 
1.      Conforming to 1.4.6Contrast (Enhanced) Level AAA creates a very 
high contrast site that is distracting and "striking" for some (many?) 
users.  "The contrast ratio of 7:1 was chosen for level AAA because it 
compensated for the loss in contrast sensitivity [by some]...users... 
People with more than [20/80 vision] usually use assistive technologies to 
access their content (and the assistive technologies usually have contrast 
enhancing, as well as magnification capability built into them). The 7:1 
level therefore generally provides compensation for [some users] who do 
not [have their] assistive technology. . . ". Therefore, in my opinion, 
requiring 7:1 contrast level all the time on all content is akin to 
requiring a one size fits all contrast setting that is not in harmony with 
the principles of web accessibility and a one size fits one through 
transformation technologies in the browsers and AT, not provided by the 
web site owner.
2.      Conforming to 1.4.9Images of Text (No Exception) Level AAA:  would 
also require no logos, no images of text, no exceptions.  I'm sure SVG is 
making progress and being adopted in many places, but I do not think we 
are at a point yet that we can require 1.4.9 on all web sites all the 
time, hence that is at least one reason it is level AAA. From a cognitive 
disability perspective, logos help with branding recognition of which 
website the user is on.  I would never recommend an "East Berlin" look (if 
you ever visited East Berlin before the wall came down you would know what 
I mean) for all websites.  However, it could make sense to require this 
level AAA criterion in some limited cases, for a controlled set of users, 
such as a set of AT training pages, hence its level AAA.  But I do not 
believe sighted users with some cognitive disabilities or aging users 
 would ever benefit.  Most of us are thinking, isn't that the role of the 
assistive technology, screen readers, etc, for most web sites and the 
answer is of course, hence level AAA.
3.      Conforming to 2.4.10Section Headings Level AAA:  would require 
section headings, "This provision is included at Level AAA because it 
cannot be applied to all types of content and it may not always be 
possible to insert headings. For example, when posting a pre-existing 
document to the Web, headings that an author did not include in the 
original document cannot be inserted. Or, a long letter would often cover 
different topics, but putting headings into a letter would change the 
letter. However, if a document can be broken up into sections with 
headings, it facilitates both understanding and navigation".  So you see, 
in my opinion, section headings are very important to some users for 
better comprehension, easier understanding, etc.  Its level AAA in my 
opinion also because of the difficulty of applying it all the time by the 
web owner.  New simplification and summarization technology is emerging, 
but we would not want to necessarily change the original content all the 
time in all cases - hence it would remain a level AAA.

So, moving a success criteria from level A to double A is not necessarily 
increasing the importance or benefit to all end users any more than moving 
it from level AA to single A is not lowering the importance or benefit to 
all end users.   However, moving a success criteria from double AA to 
single A (or adding a success criteria to level A) *is* about increasing 
the amount of responsibility and work onto the web content owner and 
increasing its applicability by requiring the criterion to be applied to 
all (or more) content, for all (or more) web sites and to all (or more) 
audiences all (or more) of the time.  Remember that it is the web content 
accessibility guidelines WCAG , not the end user experience guidelines.  
WCAG conformance is about whether the web content conforms to the standard 
by passing the testable success criteria.  Browsers, AT, and end users 
settings are all still part of the equation.  There are also
standards for the browser, called the User Agent Accessibility Guidelines 
UAAG, that  browsers should conform to.  See the discussion on essential 
components for more background.  
Please, lets stop the misunderstanding that WCAG conformance is the end 
all and that the levels are about importance.

  So you mean in WCAG2.1 some provisions will be raised from  AA to AAA   
or   A to AA?
It is my personal understanding that the importance of success criteria in 
WCAG 2.1 cannot be made less important.  So an A would not go to AA.  WCAG 
2.1 by its definition must ensure that if something passes WCAG 2.1 at a 
given level it would also pass WCAG 2 at the same level.
What is a possibility is that a success criteria might get more 
important.  So a level WCAG 2 AAA criteria might become WCAG 2.1 AA or a 
WCAG 2 level AA might become WCAG 2.1 level A.

You cannot change a normative part of a standard after it has been issued. 

There has been some discussion of a new  WCAG 2.1 ? and some discussion in 
that about raising some of the provisions from AA to A   or AAA to AA 
but going from AA to AAA would be lowering an SC?s level

Hi All,
I?m curious to know if the WCAG 2.0's  success level criteria  will be 
raised from AA to AAA in near future .
