Relationship of ISSUE 008 with ISSUE 021

The Sept 2004 version of WS-policy attachment includes the following 
section:
"
4.1.4 Message Policy Subject The following WSDL/1.1 elements are used to 
describe messages:
• wsdl:message
• wsdl:portType/wsdl:operation/wsdl:input
• wsdl:portType/wsdl:operation/wsdl:output
• wsdl:portType/wsdl:operation/wsdl:fault
• wsdl:binding/wsdl:operation/wsdl:input
• wsdl:binding/wsdl:operation/wsdl:output
• wsdl:binding/wsdl:operation/wsdl:fault

The current WS-RM policy spec attaches policy at the endpoint subject level.

If we could attach the Qos policy for DA at the message subject level, 
we would be in a better
position to express the desired semantics for Reliability of a WSDL 
Request/response operation.

For example, exactly once, ordered could be attached to the request 
message, while no reliability qos is attached to the response.

Other examples could attache reliability DA levels to the response 
message as well.

Thus I now see that Issue 008 on granularity of reliability policy 
attachment, and Issue 021 on reliability for two way exchanges
should be discussed together.
