OK.

OK.

I would prefer that as well, but it's not the case for HTML5 as of now.

head/@profile has it's issue already 
(<http://www.w3.org/html/wg/tracker/issues/55>). I can add an issue or 
bug for meta/@scheme, but these are only the ones I happen to be aware 
of right now. Producing a complete list would be good, but is more work.

Before we do that, we probably should decide whether HTML5 is supposed 
to describe all elements/attributes of previous specs or not.

If the answer is "yes", it needs to incorporate references to past 
specs, optimally lists of elements/attributes describer over there. It 
then can take over the media type registration, and we'll also have to 
figure out how to change the status of RFC 2854 in the RFC Index.

If the answer is "no", then the media type registration should live in a 
separate document. That could be either a W3C document, or just an 
update to RFC 2854. (Which, as Larry pointed out, doesn't need to be 
done right away and wouldn't block LC).
