That really doesn't seem to justify to mix HTML5 model and parsing!

Especially if you consider the amount of pages that expect the case  
corrections to be not made (considerably more neglectable than the  
amount of XHTML URLs out there!).

I guess it would be acceptable to say that a DOM revision for this  
accepts case-insensitivity.

My suggestion. It seems to be XHTML5 now, which is fine to the peace  
of now.

That's all there should be about it: converting HTML5 to XHTML5.

That tastes like good news.
I really insist it would be nice to separate the specs!

yes, I understand that for sure, and I also understand that this  
involves refining the parser by appropriate heuristics.
