    III Issues
    
           Issue #34
           Erik raised "import circularity" issues introduced in v3 as a
           result of Policy Issuer being required for the Policy Schema.
    The TC
           discussed how best to deal with this. The general consensus of
           the TC that the Context and Policy Schemas be merged.
    
           Issue #5: Policies included in a decision request
    
           Anne will repost her proposal on the list in response to
           discussion on the list.
    
           Anne proposed semantics for policies that are provided by a PEP
           as part of an authorization decision request.  The version in
           http://lists.oasis-open.org/archives/xacml/200701/msg00013.html
           was generally approved, with three changes: 1) these policies
           will be part of the SAML XACMLAuthzDecisionQuery, not part of
           the core Request Context, 2) Change "MAY" to "MUST" in: "the
           policies MAY be used by the PDP for evaluation of the current
           authorization decision request only", 3) make it clear that the
           combining algorithm by which these policies are combined with
           other applicable policies is the one in the "top level/root
           policy" used by the PDP, and not some new combining algorithm.
           Anne will redraft this for inclusion in the next release of the
           2.1 version of the XACML SAML Profile.
    
    
           Issue #35: Attribute timing
    
           The issue concerns a PDP that wants to advertise whether it uses
           Attribute values as of the time of policy evaluation vs.
           Attribute values as of the time the policy was issued.  Anne's
           proposal is that these options be included in the mechanism
           proposed in Issue #36: PDP metadata; in fact, attribute timing
          is already listed in that issue as a potential metadata element.
          The TC approved this approach to advertising attribute timing,
          so Issue #35 is CLOSED.
    
           Issue - New
           Erik reviewed an earlier discussion on Administrative Policy
           reduction and will post and outline of the Issue and a proposed
           solution to the list.
    
    meeting adjourned.
