It seems to me -- in len's terms --  that the whole point of XHTML is to 
the UIVM from hard-coded HTML towards a more general XML processing
model.  XML browsers have the potential for recognizing namespaces other
than HTML (as well as other MIME types such as PDF or Flash) for their
extensibility model.  This has all sorts of potential advantages, e.g. 
web pages that have embedded SVG images rather than Web pages that
cause separate HTTP requests for each JPG image. ... or generic XForms
processors. Sheesh, for all the pain that namespaces have created, it would 
be really nice to get some tangible gain :-)

Of course, one doesn't NEED HTML semantics built into such an XML-aware
UIVM, but as a practical matter it's needed for legacy reasons (as len

I dunno. That will take some diplomacy and dialog, I'm sure ... not to
mention some unpleasant choices between greater and lesser evils.
