> I’m Austrian and try to learn a11y-Slang and therefore misunderstand and missformulate sometimes. You wrote: “Assistive technology support should generally be good but may need to be checked for the technology stack you are trying to support.” Isn’t AT support essential in any technology stack? What did I understand wrong in Your formulation?

All I was trying to say is that in order to make a claim of WCAG conformance you need to define and evaluate whether the techniques used to meet the success criteria are supported by the user agent and assistive technology that you are using to make the claim. That is -- your implementation doesn't have to work with all user agents or assistive technologies -- strictly speak it only has to work with one -- but most experts agree that two is needed -- which assistive technology and user agents are not defined but the access to content should be taken into account during this determination. For example, for an internal site where an organization can control the technology used a smaller set of technology is likely sufficient. However for public access a broader set of technology support is likely needed -- but broad doesn't mean all although the goal is more support by more user agents and assistive technology.
