Description Ashok Malhotra 2006-08-01 17:15:09 UTC
Section 3.4 of the PolicyAttachment document introduces an External Policy attachment mechanism that uses a domainExpression to refer to the policy subject. But there is little discussion of what domain expressions can refer to.  My note, suggests domainExpression designs that allow a WSDL 1.1 definition, a http message or a JMS message to be referred to as a policy subject.  SUGGESTION: Add some discussion of domainExpressions using examples from my note above.
Comment 1 Ashok Malhotra 2006-08-15 13:07:52 UTC
The external Policy Attachment mechanism uses a PolicyAttachment element to associate a Policy with a Policy Subject.  URI References to policy subjects may include WSDL component references, (see Appendix to the WSDL 2.0 spec for URI structures to refer to WSFL 2.0 contsructs), endpoint references and other domain specific configurations and protocol constructs, such as URIs used to designate JMS queues. 

This needs to be clarified in the PolicyAttachment document.
Comment 2 Ashok Malhotra 2006-09-06 17:19:09 UTC
On the Sept 6, 2006 telcon we agreed to add the following explanatory text:

"Domain Expressions are used to identify entities such as endpoints,
messages or resources with which a policy can be associated. For
example, Domain Expressions may be used to refer to WSDL 1.1
definitions, WSDL 2.0 components, endpoint references, etc."
