I absolutely agree with this.

...as opposed to yet another protocol ;? Protocols are used for all kind
of purposes and exhibit all kind of properties and diving into what
constitutes a protocol and how they can be classified is nothing less
than a PhD subject.

The discussion that we have had about the SOAP processing model will
tell you that there is more than merely a wrapper - there is in fact a
processing model that defines how to deal properly with SOAP messages
and when to generate faults.

It is true that SOAP by itself doesn't define many of the application
layer characteristics that most other application protocols exhibit such
as message exchange patterns, routing, correlation, etc. The reason
being that I think we believe we have a good extensibility mechanism
that allows us to add such features. Time will tell whether this is a
valid assumption.
