    1. Vote on approval of minutes from March 16 meeting
         Motion: Bill
         Second: Anne
         Approved unanimously
    
    
    2. XACML Policy Model
        Hal proposed that we hold off posting Anne's XACML write up pending
        his completion similar work he is doing. The intent is to possibly
        create a paper.
    
    
    3. Proposal for Access Permitted (Issue 23)
        Hal presented this in response to a request from a developer.
    
        Erik offered that this is similar to the Delegation model.
    
        Anne suggested that we should consider circularity. Ron, noted that
        this is typically detected at the time of evaluation, not up front.
    
        Hal requested that the TC work up some Use Cases to help define the
        problem.
    
        Anne raised questions on the granularity of attributes replaced.
    
        Bill offered that this model seems well suited for addressing
        the "profile" approach.
    
        David noted this is similar to a model that VHA uses, which will be
        presented in Atlanta VHA Infosec next week. David has offered that he
        will write up a Use Case for physicians delegating to patients.
    
    4. Questions on "Introducing attribute categories"
        The TC will continue to review and discuss Daniel's proposal. There
        has not been a formal vote to adopt this change, however there is
        general consensus that this direction has merit.
    
        Hal proposed that the Core Specification will need to be rewritten
        for v3.
    
    5. Status on SAML Profile Updates
        Anne has taken our errata against the current SAML profile and
        has generated a draft with the intent of generating a Committee
        Draft. Anne is currently working on the draft to incorporate named
        elements.
    
    6. General Business
        NOTE: The next TC meeting will cover further Issues. Members are
        encouraged to prepare for discussion on propriety, status and details
        of open Issues from where last meeting left off.
    
        Erik will postpone updates to the draft until the Issue review has
        been completed.
    
    meeting adjourned.
