Hi all,

I just wanted to let people know I'm still trying to figure out out to 
word accessibility support (B.2.1.X Decision Support) in a testable way.

One possibility might be to limit the scope to problems inherent with 
the content being inserted - not more holistic problems caused when the 
content is inserted (which would be better handled by a checker).

And I'd also like to continue our practice of not dictating any 
particular workflow.

If anyone has ideas, it would be great to hear them.
