application/xhtml+xml doesn't enforce well-formedness either. That's the 
job of the parser.

If a server sends text/html, and the resulting character stream parses 
as well-formed, then it is well-formed. If it doesn't, it isn't. What 
matters more is what the stream is, not what the server says it is. 
(Yes, I know there are a few details about character encoding detection 
that come into play here. That doesn't change the point, though.)
