One problem is that the validator allows  
xmlns="http://www.w3.org/1999/xhtml" to be omitted for instance. Another  
problem is that authors write scripts that don't guarantee well-formed  
output. Yet another problem is that there are some differences between  
XHTML processed as HTML and XHTML processed as XML such as scripting,  
styling and XHTML syntax differences. In XHTML you can write <textarea/>  
in theory, but not when it's processed as HTML, etc.

That's sad.
