Right now, the spec reads more like a position paper, i.e. a statement of
direction, elaborating a policy decision, rather than a complete formal
spec.  The issues with it are thus more substantive than technical.

I assume you're talking about Section 4 and Appendix C - i.e. that even
the infinitesimal fraction of HTML documents today which manage, perhaps
by accident, to be SGML-compliant still won't be XML-compliant.  And the
insignificant minority of "editors" and the like which manage to extrude
SGML-compliant HTML will have to be modified also. 

The biggest nudge-nudge-wink-wink of all, of course, has to do with "user
agents".

Well, SGML was always a poor fit for HTML-in-practice.  XML is an even
poorer fit.

I think that's the intent of Section 1 "What is XHTML?"

: XHTML is a family of current and future document types and modules that
: reproduce, subset, and extend HTML 4.0 [HTML].[...] The details of this
: family and its evolution are discussed in more detail in the section on
: Future Directions.

I agree, though, that an explicit statement to incorporate semantics would
have been nice.
