I think this is a communication thing. Though often it seems that the accessibility community thinks more about the consumers of information than the creators. I have even seen a package with “Authoring” in the title and mentions of content creation, but the company doing an accessibility audit did not mention ATAG in their audits.

This is something that should be thought about for the next round of conferences.

Perhaps:
“When is WCAG not enough?”
“How to ensure your CMS meets ATAG.”
“Automated testing of web authoring platforms.”

Are there resources currently available for ATAG besides checklists from the W3C? I certainly don’t remember seeing much information beyond the official standard.

Good points Sean, and I agree
         One part of the puzzle which I feel is missing and is foundational in my thinking. Is the development environment.
but where is the advocacy and regulations for requiring ATAG (https://www.w3.org/WAI/intro/atag) compliant development environment?  Why isn't ATAG conformance a requirement for authoring tools, integrated development environments, frameworks, etc, just like WCAG is for web sites?

All,



This is a very important and valuable discussion. One part of the puzzle which I feel is missing and is foundational in my thinking. Is the development environment.



To many development tools do not have accessibility built into them. Many discussions over the years have been focused on this with very little change. If the tools do not include accessibility in their UI, then you have problems regardless of the design and intention of the organisation.



The concept I used, if you design the best house and build a substandard foundation. Then your fantastic house will have some serious structural problems. UX designers do get the concept. Developers get the concept. But the development tools fail in relation to accessibility. I regard the development tools as the foundation of your product. The developer and UX/UI designers are the design part of the house.



Linking this back to the thread. if the foundation of the product had accessibility built in. then there is no need to know what assistive technology is being used. As the user will get the same experience as all other users. At least this is the goal.





Leveraging off what already has bene discussed on the thread. Accessibility has to be core in any software product regardless if it is web, desktop, mobile or whatever. Thus why the discovery and design stage is so important.

the way to make it a reality is to simply follow the guidance in the link Mark providerUnderstanding Accessibility Support<https://urldefense.proofpoint.com/v2/url?u=https-3A__www.w3.org_TR_UNDERSTANDING-2DWCAG20_conformance.html-23uc-2Daccessibility-2Dsupport-2Dhead&d=DwMFAw&c=jf_iaSHvJObTbx-siA1ZOg&r=aWgRqmoh0Xuzjf7UaXq44Tf6K41u809DPE44ioVTOvk&m=opIGfHbrrw3NadMKP6MndpJw0lv0j2Ws1wGnb5Zd89o&s=X3my5_8xEgnc-4NNRolcJtGMP1sXWTYvOYZR7blnQp4&e=>:
"When new technologies are introduced, two things must happen in order for people using assistive technologies to be able to access them. First, the technologies must be designed in a way that user agents including assistive technologies could access all the information they need to present the content to the user. Secondly, the user agents and assistive technologies may need to be redesigned or modified to be able to actually work with these new technologies.

"Accessibility Supported" means that both of these have been done and that the technology will work with user agents and assistive technologies."


Clearly there has to be acceptance that user agents and assistive technology may need to be redesigned or modified to be able to actually work with new technologies.  Is WAI-ARIA an example of a new technlolgy designed in a way that user agents *could* access all the information they need to present the content to the user - yes I believe there is general consensus.  Did user agents and assistive technologies get redesigned and modified to be able to *actually* work with WAI-ARIA - yes I believe there is general consensus.  So WAI-ARIA is an example of a new technology that is actually accessibility supported in at least English and other languages, on the Windows and other platforms, in Firefox and other browsers, and NVDA, JAWS and other assistive technologies.

So, going back to Mark's original question:
"Related to AT detection is how can a site or app know what web content technologies to serve up that are accessibly supported without knowing the user agents and AT the user is using?"

The site doesn't need to know which AT is being used by the user at the exact time the page is loading, but that the site or app *can* know what web content technologies to serve up by knowing which ones are supported *if* there are user agents and AT that support it - then it *will* work - becasue it has been tested to validate so.  The Understanding WCAG document goes on to say that there is a need for an external and international dialogue on this topic. Some notes to help in understanding and exploring this topic:

1.        Accessibility support of Web technologies varies by environment

  *   Web technologies may only need to be supported by those specific user agents and assistive technologies deployed at a company. (These may be older versions of user agents and assistive technologies or the very newest versions).
  *   Content posted to the public Web may need to work with a broader range of user agents and assistive technologies, including older versions.
2.        Accessibility support of Web technologies varies by language (and dialect)

  *   There are different levels of older assistive technologies support in different languages and even countries. Some environments or countries may provide free assistive technologies.
3.        New technologies won't be supported in older assistive technologies

  *   Clearly, a new technology cannot be supported by all past assistive technologies, so requiring that a technology be supported by all assistive technologies is not possible.
4.        Support for a single older assistive technology is usually not sufficient

  *   Support by just one assistive technology (for a given disability) would not usually be enough, especially if most users who need it in order to access content do not have and cannot afford that assistive technology. The exception here would be information distributed to company employees only where they all have one assistive technology (of that type).
5.        Currently assistive technology that is affordable by the general public is often very poor

  *   Creating content that can't be used by the general public with disabilities should be avoided. In many cases, the cost of assistive technologies is too high for users who need it. Also, the capabilities of free or low cost AT is often so poor today that Web content cannot be realistically restricted to this lowest (or even middle) common denominator. This creates a very difficult dilemma that needs to be addressed.

And then the Understanding WCAG document includes Examples of Conformance Claims<https://urldefense.proofpoint.com/v2/url?u=https-3A__www.w3.org_TR_UNDERSTANDING-2DWCAG20_complete-2Ddiff.html-23uc-2Dexamples-2Dhead&d=DwMFAw&c=jf_iaSHvJObTbx-siA1ZOg&r=aWgRqmoh0Xuzjf7UaXq44Tf6K41u809DPE44ioVTOvk&m=opIGfHbrrw3NadMKP6MndpJw0lv0j2Ws1wGnb5Zd89o&s=4G9SS5Zi3rv75ToaHo1s_QcpQNcMK01_BKh8r8M8EEo&e=>that list
       - the technologies that this content "relies upon" is: blah blah blah
       - the content was tested using the following user agents and assistive technologies: blah blah blah

So, the web site owner *can* document a claim (but doesn't have to document the claim per WCAG) how they validated (or tested or determined or what ever English phrase they want to use) it confoms to the success criteria.  The Information Industry Technology Council (see https://www.itic.org/policy/accessibility<https://urldefense.proofpoint.com/v2/url?u=https-3A__www.itic.org_policy_accessibility&d=DwMFAw&c=jf_iaSHvJObTbx-siA1ZOg&r=aWgRqmoh0Xuzjf7UaXq44Tf6K41u809DPE44ioVTOvk&m=opIGfHbrrw3NadMKP6MndpJw0lv0j2Ws1wGnb5Zd89o&s=0jI9Zk9TylMKi7r_Hy5wBitCDQSC2nUE29gm4r5jjVs&e=>) includes a section in the Voluntary Product Accessibility Template®, or VPAT® 2.0for reporting conformance:
". . . 4.        A report must contain the following content at a minimum:
•     . . . Evaluation Methods Used – Include a description of what evaluation methods were used to complete the VPAT for the product under test.. . .
ITI suggests that authors adopt the following best practices when using the VPAT®to create an Accessibility Conformance Report. . . .
•     Evaluation Methods Used – Information to enter may include the following:
•     Testing is based on general product knowledge
•     Similar to another evaluated product
•     Testing with assistive technologies
•     Published test method (provide name, publisher, URL link)
•     Vendor proprietary test method
•     Other test method "
Even after all this designing with users and testing with browsers and assistive technologies and documenting the conformance, there still can be a delimina, as I try to remind Bob and others [quoting from the 2017 Understanding Accessibility Support<https://urldefense.proofpoint.com/v2/url?u=https-3A__www.w3.org_TR_UNDERSTANDING-2DWCAG20_conformance.html-23uc-2Daccessibility-2Dsupport-2Dhead&d=DwMFAw&c=jf_iaSHvJObTbx-siA1ZOg&r=aWgRqmoh0Xuzjf7UaXq44Tf6K41u809DPE44ioVTOvk&m=opIGfHbrrw3NadMKP6MndpJw0lv0j2Ws1wGnb5Zd89o&s=X3my5_8xEgnc-4NNRolcJtGMP1sXWTYvOYZR7blnQp4&e=>] that the capabilities of free or low cost AT is often so poor today that Web content cannot be realistically restricted to this lowest (or even middle) common denominator. This creates a very difficult dilemma that needs to be addressed.
I believe this *is* being address by non-profit organizations, governments, corporations, and other initiatives that are providing "1st Class" low cost internet access, assistive technologies, and funded research:
       organizations such as Benetech, technology for social good at https://benetech.org/<https://urldefense.proofpoint.com/v2/url?u=https-3A__benetech.org_&d=DwMFAw&c=jf_iaSHvJObTbx-siA1ZOg&r=aWgRqmoh0Xuzjf7UaXq44Tf6K41u809DPE44ioVTOvk&m=opIGfHbrrw3NadMKP6MndpJw0lv0j2Ws1wGnb5Zd89o&s=afrB7tUO_CkeN0lwiMQKdXwr6z8kYfqjj4d1zARvD-k&e=>,

I hope a productive conversation can continue.  The WCAG Working Group see conversations around levels of "accessibility supported" as necessary and complex (see the section under the heading "Level of Assistive Technology Support Needed for 'Accessibility Support'<https://urldefense.proofpoint.com/v2/url?u=https-3A__www.w3.org_TR_UNDERSTANDING-2DWCAG20_conformance.html-23uc-2Daccessibility-2Dsupport-2Dhead&d=DwMFaQ&c=jf_iaSHvJObTbx-siA1ZOg&r=aWgRqmoh0Xuzjf7UaXq44Tf6K41u809DPE44ioVTOvk&m=I1O2ZAgFrv7IGd5ZUe4eQIC1pLLvsIbVWkcR3c7UcRU&s=RECn_HIUpoUnb4nHeDntOs0rvP1a423o_JMY8UCEXWU&e=>"). Item 5 in the list addresses Bob's point and Phil's number 4. Can anyone add more to the discussion?

What's the way to make "accessibility supported" a reality?

but Bob,
there are so many things we do agree on though, like
1. Web applications should be developed to accommodate assistive technology without the web application knowing if the user is using assistive
technology.
2. Web application should comply with WCAG 2.0 Level A and AA Success Criteria.
3. Internet access should be affordable to everyone.
4. Assistive Technology should be affordable to everyone.
