I'd question what is inherently "better" about strict or XHTML, with regards
to accessibility?

I'd posit that even valid HTML4.01 transitional can be
accessible provided that the other WCAG2.0 checkpoints (and associated
html/css techniques) are followed (and effectively, if you follow things like
the  separation of content and presentation, even if you declare HTML4.01
transitional, it will end up looking more like HTML4.01 strict anyway)

But the idea of the main WCAG2.0 document is to remain technology agnostic.
Adding this sort of detail sounds like a bad move. And, to paraphrase Alastair:
if you use XHTML you need to make damn sure it validates anyway. If you can't
guarantee validity for whatever reason (lack of knowledge, resources, whatever)
then stick with HTML (but make sure that's valid).
