Well, HTML4 and XHTML1 aren't technically compatible -- even disregarding 
the DOCTYPE and namespace issues, an arbitrary conformant HTML document is 
typically not a conformant XHTML1 document, and vice versa.

It is possible to serialise an HTML4 DOM into either HTML4 or XHTML1, 
though, and the same is possible (more explicitly) with HTML5/XHTML5 as 
defined by the Web Apps spec.

SGML simply doesn't have the ability to define error handling rules to the 
level of detail HTML5 requires.
