Description Ashok Malhotra 2006-08-29 14:32:27 UTC
A possible Policy processing model is as follows:  the two parties get access to each other policies (in a manner not specified in the framework) and select a Policy alternative that that appears in the Policies of both parties.  This Policy alternative is followed in both directions.  But there is no mechanism to communicate the selected alternative to either party.  Note that there may be more than one alternative in the two policies that matches and there is no simple algorithm to determine which alternative is selected.  There is also the problem of ensuring, in this case, that both parties select the same alternative from competing, matching alternatives.  This lack of knowledge makes it difficult for the Policy compliance engine check whether a message adheres to the Policy it is supposed to.

We need three things:
1. An algorithm to select a single alternative if more than one alternative in the two policies matches
2. A mechanism to indicate the selected alternative
3. An ability for the message to indicate the policy alternative it is following

RESOLUTION: Close #3639 with no change to the policy spec but ensure that guidelines document provides adequate explanation of our logic for not dealing with this in 1.5
