I'm going to weigh in on Ian's side on this one.  I believe that we should
"keep it simple" by spcifying no application payload be allowed in the SOAP
Body.  That's a perfectly legal thing to do as Rich Salz noted.  If we
wanted header and payload in the same XML document, why was there no "body"
element in the original ebXML message structure?  Answer: we didn't want
them in the same XML document for good reasons.

Chris, you wrote:

and I wholeheartedly agree.  However, while the payload content is the
purview of the BP designer, the way in which that content is packaged into
the ebXML message is *not*.  That is our domain and we should strive to be
as explicit and as deterministic as possible.  Leaving packaging decisions
up to individual business domain experts can only lead to an increase in
complexity and a corresponding decrease in interoperability.

This same issue arises with the handling of multiple payloads within a
single message.  Should we specify that there can be only one payload part
that can contain many fully qualified ebXML messages (as we used to) or do
we move to the flat model shown in SOAP w/Attachments examples?  Or do we
allow both?  Again, I believe we need to be explicit here and pick one and
force the business domain experts to follow a single packaging scheme.  In
this particular case, I don't care which we pick, but IMHO believe we should
only pick *one*.

This is already provided for as the Reference xlink:href is an URI
value which includes the xpath/xpointer subset of URI values.
