Subject: RE: [xacml] Groups - Discussion: Proposed PAP Architecture uploaded
The currently agreed ABAC architecture (PDP, PEP, PIP, PAP) is deployed in many different environments and explicitly permits proprietary extensions in various places. I don’t accept that we cannot find further architectural elements which we can agree on which will be beneficial to organizations deploying XACML. I could be persuaded after discussion, but I don’t see limiting ourselves a priory. I don’t understand the relevance of your point about metadata. If metadata is embedded in policy syntax, it should use existing extension points or special comment formats like Java does. Other PDPs should be able to evaluate policies without any of the enhancements. Otherwise XACML does not provide interoperability. Perhaps a better way to make progress is try to agree on a set of requirements which are basic to the standard and identify areas for proprietary extension.
