The HTML WG did think so, too, and the first Proposed Recommendation of
XHTML 1.0 said [1]:

  5.1 Internet Media Type

    Work is currently in progress to determine how Internet media types
    [RFC2046] should be used when delivering XML documents, and this will
    be the subject of a future W3C document.

    Since XHTML is an XML application, XHTML documents may be delivered
    using the Internet media type text/xml or type application/xml
    [RFC2376]. Additionally, since one of the aims of XHTML is to allow
    migration from existing HTML user agents to XHTML user agents, XHTML
    documents may be delivered using the Internet media type text/html. In
    this case, it is recommended that the documents follow the guidelines
    in Appendix C to decrease the chance of document processing failure.

But we've got a number of objections to use "text/xml" or "application/xml"
for XHTML, so the first XHTML 1.0 PR had to be returned to the Working
Group.  That's why section 5.1 of XHTML 1.0 REC had to be silent about
"text/xml" or "application/xml".
