Actually, there's no reason not to develop a complete and interoperable
mapping between MIME and XML. This would create an XML native transport
protocol (XMTP? or SXTP? hmmm :-). People with validating parsers could turn
off acceptance of undefined MIME types etc. e.g. "application/x-whatever".

What do people think this mapping should look like. Based upon some of the
work we are doing, we have a need for this and will probably develop a
mapping ourselves unless there is an interest from others in specifying
this.
