Re: [ebxml-cppa-negot] Abstract WSDL

[Martin Sachs <m.w.sachs@post.harvard.edu>]

This is a good beginning.   What I see is a very simple replacement for the
BPSS instance in the current specification. However as Matt has previously
pointed out, its simplicity is obtained by leaving most of the protocol
matters to the message definitions, so there is work to be done there
before we have something usable.

Before defining the message contents to include the protocol definitions,
we should first work on the service and binding definitions (see the
Documentation element below), which are needed to make the messages
flow.  Once we have the service and binding definitions, we can learn from
them how to produce a really simple negotiation CPP and thus a really
simple negotiation CPA that will get us well along to the goal of a much
simpler specification for version 1.

Is anyone interested in taking a first cut at the service and binding
definitions for SOAP?  The WSDL spec probably contains a sample SOAP
binding definition (at least WSDL 1.1 did) that will do most or all of what
we need.  The service definition will be somewhat related to negotiation, I
assume.

Regards,
Marty.
