Well HTML is written in SGML (allegedly) not XML so has no XML
namespace. That gets rid of three of these; if the HTML WG would kindly
give XHTML one namespace then it would be possible to have justa single
declaration to cover XHTML.

People are likely to need somewhat different style sheets for XHTML and
for HTML in any case, because of limitations and constraints on HTML
processing (certain elements are always block, always have 40px left
margin, and so on) whcj do not (should not) apply to XHTML.
