ATAG conformance indicates that machine verification has been done on 
the input, wherever it comes from. I think that's good enough to be able 
to say that Web bulletin boards, weblogs or other content management 
systems that conform to ATAG should in fact conform to WCAG, including 
external contributions.

I am not interested in attempting to say that any site that allows 
community participation must be inaccessible. I think that sites like, 
say, Accessify Forums, may take issue with that as well.

We need to be a little more clear with what the problem really is, and 
to what extent it can be fixed. Content that is syndicated from a 
newswire isn't going to get much more accessible (except insofar as you 
can add the title as alt text, for example). Video content provided 
without captions or descriptions and updated hourly are likewise not 
going to be made accessible in a timely fashion. And they'd fail ATAG 
anyway, if that's the case.

ATAG-conformant products produce WCAG-conformant content on a reasonably 
reliable basis. It's as good a marker as we've got.
