Certainly not -- DOM consistency is a great idea. But given that the
HTML5 spec defines how the DOM is built, there's a very simple solution
to that -- HTML5 could simply mandate that:

	<html xmlns:foo="http://foo.example.com/">

generates an identical DOM representation in both XHTML5 and HTML5.
What's the problem with that? 

In existing implementations, there are differences, sure. But for the
most part, those differences are pretty small and obscure, and don't
actually effect real world code very much. e.g. the following code seems
to work fine in Opera, Firefox and Midori (a Webkit browser):


The files are byte-for-byte identical (indeed, on disk, one is just a
symlink to the other).
