FWIW, I was involved in the discussions around Sun's decision on this
point, and my lone contribution to RFC 3023 was intended to keep awareness
of this issue alive;

  "An XML document labeled as text/xml or application/xml might contain
   namespace declarations, stylesheet-linking processing instructions
   (PIs), schema information, or other declarations that might be used
   to suggest how the document is to be processed.  For example, a
   document might have the XHTML namespace and a reference to a CSS
   stylesheet.  Such a document might be handled by applications that
   would use this information to dispatch the document for appropriate
   processing."

The emphasis here is on *might*.  application/xml and text/xml have
no defined or even defacto behaviour for namespace dispatching.  It
would be wonderful to be able to retrofit that behaviour on top now, but
that could prove problematic given that not all XML applications follow
the convention that a namespace can be used to trigger a processor; the
XSLT simplified form, for example.  There may very well be other
examples.

In short, the more things change, the more they stay the same. 8-(

My plan to address this is to define a new generic XML media type that
can be used for content that expects this type of processing behaviour.
