Subject: 26. Define policy reduction (partial evaluation) of a policy
Issues raised during discussion at F2F 21 Oct 2003: This item was closed for XACML 2.0. The Grid requirements can be met by giving the evaluating PDP access to necessary attributes and sub-policies. PROPOSAL: http://lists.oasis-open.org/archives/xacml/200310/msg00042.html #26 1. The internal, parsed representation of a policy may not be reversible to create a new reduced XACML Policy or PolicySet instance. 2. The resulting policy will rarely be simple enough to be much help in analysis or debugging: most of the policy will still contain references to missing attributes. Anne -- Anne H.
