Well, MIME media types are not just 'names', they're specifically
used to invoke different kinds of processing



section 7:

   XML generic processing is not always appropriate for XML-based media
   types. For example, authors of some such media types may wish that
   the types remain entirely opaque except to applications that are
   specifically designed to deal with that media type. By NOT following
   the naming convention '+xml', such media types can avoid XML-generic
   processing. Since generic processing will be useful in many cases,
   however -- including in some situations that are difficult to
   predict ahead of time -- those registering media types SHOULD use
   the '+xml' convention unless they have a particularly compelling
   reason not to.

So the question is whether it is desirable that intermediaries
might intercept and process SOAP messages using XML-generic
processing. If it is, then application/xp+xml or application/soap+xml
is appropriate. If not, then application/xp is appropriate. In neither
case is application/xml or text/xml appropriate.
