Subject: Rationale for Approval Despite SAP NO Vote

Jacques and I drafted the following text, as a rationale for appoving 
the WS-Reliabiity spec, despite the SAP NO vote.

We should discuss this text at the F2F meeting before our vote to 
approve the spec.

Tom Rutt
The WSRM TC has considered the SAP comments accompanying their NO vote 
on the OASIS WS-Reliability Specification.

There is currently no standard to represent the RM capabilities 
associated with a Web Service.

Appendix B of the WS-Reliability specification (i.e., Features, 
Properties and Compositors) provides a normative WSDL 1.1 extension 
mechanism to meet this requirement.

This mechanism is normative, but optional for conformance to the 
WS-Reliability Specification.  This provides one mechanism which may be 
implemented today to realize this requirement, but does not preclude 
usage of future standard mechanisms (e.g., for WSDL 2.0).

Without specifying a representation of reliability capabilities that a 
WS endpoint can advertise, web service providers and web service users 
would have to define their own ad-hoc ways to represent and exchange 
such capabilities. The current specification provides a WSDL extension 
for describing RM capabilities which, even though optional, will 
facilitate interoperation for those who decide to use it. We do not 
think the optionality weakens interoperability in this case, as SAP 
claims. We believe that not specifying such a feature at all would make 
it harder to agree on a representation mechanism between partners.

The WSRM TC (subject to Vote on Nov 10) agreed to request the OASIS TC 
Administration to approve the specification as submitted despite the SAP 
negative vote.
