Re: One-way messaging in SOAP 1.2

Let me be explicitly clear then. What I meant
by (say a Servlet or CGI) was not meant to infer
the Servlet or CGI implementation layer, but
an *instance* of a Servlet or CGI that in effect
*is* the implementation of the binding.

Thus, neither the Servlet nor CGI *implementation*
need understand the semantics inferred, just the
layer which binds the protocol (HTTP) to the SOAP
node.

Cheers,

Chris
