Marwan,

I'm not sure that I agree. It should be possible to have the
application resolve a service endpoint at deploy or runtime
in which case the application developer need not be concerned
with the protocol, only that it satisfies/supports a particular
MEP. How that MEP is handled at the protocol level is (or should be) the
problem of the binding implementation, not the application.

A service may also be accessed via multiple protocols, and it should
be possible to shield the service implementation (application) from
the underlying protocol(s) thus allowing the same code to be
accessed via multiple channels.

Cheers,

Chris
