        changes.
    
        XACML v3.0 timing
        -----------------
        Hal offered that the TC should consider
        incorporating the broader scope of features discussed by the TC
        and not releasing a delegation centric release given the effects
        and effort associated with a release. The general consensus of the
        TC is that the list of outstanding issues be reviewed individually,
        Champions defined and the final cutoff list for v3 be made by the
        next meeting.
    
        Erik offered that the Issues list be split between a v3 list and a
        post 3.0 list to keep things cleaner. Numbering will remain the
        same.
    
        Hal noted that he will be attending the Jericho Forum in September.
    
        Rich posted his Summary on the Interop to the list for review.
    
    3  Issues
    
        #12 Erik suggested that generalized Obligations be withdrawn because
            from 3.0 because there wasn't activity by others on the list.
            Hal voiced interest in reengaging the topic within the TC.
    
        #23 Hal stated that this work in progress.
    
        #62 Hal stated that this work in progress.
    
        #66 Rich discussed how "missing attributes" was not well adopted
            during the Interop and that this area needs better definition
            to be applicable--normative definition.  Seth offered to assist
            with creating documentation to address usage/implementation
            patterns.
    
        #67 This requires Xpath expertise. The TC is looking for someone
    
        #71 Hal will evaluate possible solutions and comeback to the TC with
            a proposal or suggestion to defer.
    
        #72 The issue of where policies supplied in a 3.0 XACML-SAML access
            request end up in the PDP in relation to other policies already
            present in the PDP is currently not specified. Erik will work on
            a proposal for this.
    
        #75 Rich will evaluate this issue and comeback to the TC with a
            proposal or suggestion to defer.
    
        #76 	Hal and Erik will evaluate this issue and come back to the TC
             with a proposal or suggestion to defer.
    
        Trusted Issuer
        --------------
        Erik offered that this is not necessary because its
        use is not clear and adds undue complexity. Hal offered that the the
        TC hold off making this change and give the members a chance to
        consider this for a few weeks before removing. Erik also offered
        that the trusted issuer be required (he will post a note on this to
        the list.)
    
        V2 Compatibility
        ----------------
        Hal voiced concern about how providing backward compatibility
        affects acceptance and adoption of a new specification. Attribute
        selectors do not have a mechanism for compatibility so Hal was
        willing to concede that v3 would not be compatible with v2 attribute
        selection mechanisms.
    
        Seth asked for clarification on the normative requirements of
        "compatibility". The general consensus is that this issue is limited
        to the changes in XPath expressions with respect to the Context
        Handler.
    
        The TC needs to agree on how to limit the scope of the required 2.0
        compatibility. The current draft spec has a normative requirement  
    which
        is believed to be impossible to implement fully.
    
        V3 "Diff" Documentation
        -----------------------
        Rich is working to compile a delta between v2 and v3 features. Erik
        offered to review this directly with him.
    
    meeting adjourned.

    I have promised to look at #67, but was out of town/time recently.
    Whatever language we come up with - I should probably review it on the
    XPath working group - we have a face to face in early October.  They are
    usually very helpful with reviewing standards referencing XPath/XQuery.
