I think a good accessibility guidelines document as part of this group's
deliverables would be a good thing...but wouldn't necessarily be a
replacement for the conformance rules (existence of/lack of) within the
HTML5 specification.

I would think a guidelines document to be more along the lines of a
Primer--providing solid and consistent advice on how summary can be used
effectively, when to use alt text, when to leave the alt attribute empty,
how to provide accessible content for the Canvas element, and so on.

Rules, though, should stay in the HTML5 document. If not having any alt
attribute is a conformance violation, then it should continue to be a
conformance violation in the HTML5 spec. How the alt tag can be used
effectively, with good examples, would be better in a guidelines document.

Maybe a better option is just a good, general purpose authoring
guideline/Primer -- authoring in this case not being tools, but people
creating pages. Sort of like taking Mike's document, and adding flesh to the
bones.

We could probably move a 15-20% of the existing HTML5 specification to this
new document. And it would provide clarity as to audience, too, instead of
the mixed audience problems we have now. It would be another document, but
it's better to have several smaller, tightly focused, cleanly demarcated
documents, than one big mishmash of a thing that crashes browsers when you
access it.

I don't know if this is what Sam had in mind or not. Just stuff I've thought
about as I've gone through the HTML5 spec recently.
