RE: Abstract messages [Was: Multi-Party Binding Scenario]

David et al,
 
I am effectively agreeing with David on the principles we should attempt
to follow on this issue.

Jim 

I have a lot of sympathy for what you suggest but if we follow your idea
I honestly do not believe that the result would be usable by Groups such
as RosettaNet and all the other vertical industries that NEED to define
a choreography that can be generally used by their members.

However I do agree that we need to limit our scope so the compromise I
would suggest is to: 
1. Define an abstract bindable choreography 
2. Define how to bind the choreography to WSDL and XML 

That way, the needs of vertical industry groups and realizing limited
scope can both be met. 

Chairs, this topic is one we might want to discuss on a conference call.

Jon, Tony, 

Furthermore given the name (and charter?) of this group I would suggest
that 
tying its work to Web services (and perhaps the work of the WSAG) would
be 
the most sensible thing to do. While the notion of an abstract and
bindable 
choreography standard does have a certain undeniable appeal, I think
this 
group should really stick to a specific "binding" if you like (and XML 
Schema plus WSDL works for me because you can extend it nicely), and
that 
should be for Web services (pick the definition that best suits you, but
I 
guess things like ASN.1 are out of scope).
