Subject: Evaluating XACML as a Policy Language - Draft 3.0
Colleagues, Attached is an updated draft of the proposal I presented in http://lists.oasis-open.org/archives/xacml/200303/msg00008.html for evaluating one or more XACML policies with the goal of determining a set of Attributes that satisfies the policies. This updated draft simplifies the algorithm by recognizing that candidate Attribute values are available at the time the initial policy is evaluated. The draft also includes more details on how to handle specific constructs in XACML and points to existing Open Source code for performing the conversion of the XACML parse tree to Disjunctive Normal Form. This proposal is an alternative to the "Policy statement combination and reduction" proposal from Tim Moses attached to http://lists.oasis-open.org/archives/xacml/200303/msg00012.html Anne Anderson -- Anne H.
