A media type in a header does indeed take priority... I know this, of 
course.  My point was that, as we all know, lots of XHTML 1 documents 
get served as text/html when in fact they are really well-formed, valid XML.

If you send it as text/html, it *might* be XHTML.  Since we tell people 
they can do that.  So, since we tell them that, we should at least 
provide some way to help them validate things that they serve up as 
that.  Maybe we do this already and I don't know where the control is.
