Careful!  The "Ultimate receiver" (in SOAP speak) in that case *is*
the recipient of the message, identified by the URI, since it terminates
the message.  If it chooses to pass the data it receives along to some
other service, it needs a whole new SOAP message to do so.

IMO, it's most definitely a service.  In fact, all RESTful services
which accept documents work this way; document-in, (optional)
