   Statement #2 is incorrect. First, not all XHTML can be sent with the
"text/html" MIME type. Only XHTML that complies with Appendix C can be
sent with "text/html". Second, it is not "classified" as that MIME type.
It is "labeled" with that MIME type, and the XHTML 1.0 specification
explicitly refrains from defining the meaning of "text/html".

   (Please note that according to the XHTML FAQ, XHTML 1.1 cannot be
served as "text/html". This makes sense when you consider that, among
other things, XHTML 1.1 doesn't support the |lang| attribute.)

   Statement #3 is supported by the W3C Note "XHTML Media Types", by the

   Incorrect. XHTML 1.0 was specifically designed to degrade in such a
way that it could be handled in HTML user agents _IF_ the XHTML document
conforms to Appendix C. An arbitrary XML language is not necessarily
designed in such a manner, therefore you can't say that XHTML plus an
arbitrary XML language could be served as "text/html". And any language
that degrades into HTML in the way XHTML 1.0 does is by definition a
subset of XHTML.
