I don't agree.

Content-type: text/xml is just a MIME header that routes the
corresponding MIME part to the XML parser within the service.

The XML parser is -- by design ! -- perfectly able to decipher
the contents of the text/xml and take the appropriate action.

If the content isn't one the service understands, labeling it
any way other than text/xml won't change that.

If the content is compressed it must have a corresponding
Content-encoding or it is just garbage.

Content-type has a simple job.  Let's keep it that way.
