Ignoring the _syntax_ for a moment, there have been reasons given for 
wanting to use XML _features_ in HTML5 - the desire to embed MathML or 
SVG in a HTML document, for example. You suggest punting these use cases 
to XHTML5, without addressing the fundamental problem that the XML 
parsing model is unsuitable for the web, so denying authors the 
possibility of rich (what XML would regard as "mixed namespace") content.
