My view on this it is that SOAP provides an envelope that can
encapsulate a message.  But the *meaning* with which that message is
transferred rests (pun intended 8-) primarily with the underlying
protocol to which it is bound, but also to the SOAP features that
extend it (the end-to-end targetting model, and mustUnderstand).

Actually, this isn't a REST specific argument at all.  Every application
protocol exists to coordinate the tasks necessary for that application.
Each one accomplishes this by limiting the agreement that is made over
the network, because agreement between uncoordinated actors is *HARD*
and takes lots of time thrashing about in standards organizations.  HTTP
just happens to be able to do a lot more than other application
protocols.  Perhaps that's why it's confused for being a transport
protocol so often?
