Hi Stefan, "...who should do what with reasonable effort..." OK. What (and who) defines "reasonable"? (That BTW, is a serious question) And reasonable to whom? the end user? the content creator? the site evaluator? the non-technical legislative official? the judge? (who's judge? A German judge? A French judge? An American judge? An Australian judge?...) This is not as simple as it may sound. Also, if there is a common override concept for CSS styles to be used in user agents (a list what css attributes should be overridable to enable customization for WCAG requirements) I also think that WCAG should lay foundation to this. So, respectfully, I think there may be some confusion about the role the Accessibility Guidelines Working Group plays within the larger ecosystem. What you are alluding to here would likely first have to start in the CSS Working Group (or maybe the joint CSS Accessibility TF <https://www.w3.org/WAI/APA/task-forces/css-a11y/>?), and would likely need to have the support of the browser vendors. I will suggest that this activity, at this time, is out of scope for this WG. The role of *this* working group (per our Charter <https://raw.githack.com/w3c/wcag/charter-2019/charter.html>) is: - Develop Web Content Accessibility Guidelines (WCAG) 2.2 to address gaps in WCAG 2.0 and WCAG 2.1 related to content with a particular focus on users of mobile devices and people with low vision or with cognitive disabilities. - Continue development of a repository of test rules that uses the Accessibility Conformance Rules Format, to promote a unified interpretation of WCAG 2.x among different web accessibility test tools. - Develop a new standard (name to be decided) to succeed WCAG 2.x based on the work of the Silver Task Force. The goal is to provide information that can be used to improve the accessibility of products when using the guidelines on a variety of platforms. As noted in the Draft Requirements, it will use a different framework to allow it to address more disability needs, address publishing requirements and emerging technologies on the web such as web XR (augmented, virtual and mixed reality) and voice input. It will provide non-normative information about the ways web technologies need to work with authoring tools, user agents, and assistive technologies. This framework is intended to support better coverage across disabilities, and be easier to maintain, so that the new framework will be more durable over time as technologies evolve. This will require development of a new conformance model, engaging policy makers in that process, and testing the model with policy makers from different settings. - Maintain Authoring Tool Accessibility Guidelines (ATAG) as needed. - Continue development of non-normative documents to support implementation of accessibility guidelines. *That's it*, and I can suggest that the W3C membership (and management) do not look favorably on scope creep, so any additional work would first need to find a home, and be sure that it is in scope for whatever home if finds - again I suspect CSS Accessibility TF would likely be the initial place for that: The CSS Accessibility Task Force (CSS A11Y TF) is a Task Force of the Accessible Platform Architectures Working Group (APA WG) <http://www.w3.org/WAI/APA/>, the Cascading Style Sheets Working Group (CSS WG) <https://www.w3.org/Style/CSS/>, and the Accessible Rich Internet Applications Working Group (ARIA WG) <http://www.w3.org/WAI/ARIA/>. It assists these Working Groups to address accessibility to people with disabilities where impacted by features of Cascading Style Sheets. So, it's not so much that I am seeking to frustrate making the web more accessible, but rather I want to ensure that we get there with due and deliberate consideration, that we do so within the framework that the W3C has afforded us, and that we are realistic on what (and how much) we demand of content creators of all sites: the SAP's, Googles, Adobe's and Amazon's of the world, as well as the 3-page site for the flower shop down the road. Putting all of the heavy lifting on the content creator is both unfair and unrealistic, and WILL fail. (I'll further suggest that the CSS Accessibility TF could use some additional hands to keep up with ongoing work, never mind pursuing new initiatives, and if you feel this idea is really important, I would urge you to reach out to that TF and get involved there). The bottom line for me is that I believe we will fail whenever we attempt to try and modify author behavior by writing a SC with the hopes that it will be legally mandated. It just doesn't work that way. Respectfully JF On Thu, Apr 16, 2020 at 12:19 PM Schnabel, Stefan <stefan.schnabel@sap.com> wrote: > Hi John, > > > > Thanks for asking this.
