This is a good idea.

A general way to employ the Content-type header to specify a document type
is:

Content-type: text/xml; element="html"; fpi="-//W3C//DTD XTHML 1.0
Strict//EN";              uri="http://www.w3.org/XHTML.DTD"

This should apply to text/html, text/xml, text/sgml, application/xml etc.

deja vu all over again :-)
