    Subject: Summary of issues: WI#10. Parameters for Combining Algorithms


    This is my understanding of where we are on WI#10 (combining
    algorithm parameters).  Could people clarify if I have gotten any
    of this wrong or if I have left something out?
    
       APPROVED:
       a) Schema will be as specified in
          http://lists.oasis-open.org/archives/xacml/200403/msg00125.html
          except that <AttributeValue> will be replaced with
          <Expression> (per WI#7), which could be a <ConditionReference>.
       b) <CombinerParameter> <AttributeValue>/<Expression> elements
          will have a DataType so the PDP can completely evaluate the
          value before passing it to the CombiningAlgorithm.
       b) <CombinerParameters> are children of the <Policy>, not of
          the <Rule>; i.e. they are specified outside the <Rule>
          elements to which they apply.
    
       ISSUE:
    
       How are <CombinerParameters> elements and the
       <CombinerParameter> elements within them associated with
       particular <Rule> elements?  Options:
    
       a) Left completely up to the CombiningAlgorithm.
    
          Polar's preference.
    
       b) Specified order: all <CombinerParameter> elements in the
          1st <CombinerParameters> element are associated with the
          1st <Rule>, the 2nd <CombinerParameters> are associated
          with the 2nd <Rule>, etc.
    
       c) Specified in <CombinerParameters> metadata.  E.g.
          <CombinerParameters ParameterRef="Rule5">
             <CombinerParameter ParameterName="p1".../>
             <CombinerParameter ParameterName="p2".../>
          </CombinerParameters>
          <CombinerParameters ParameterRef="Rule2">
             <CombinerParameter ParameterName="p1".../>
             <CombinerParameter ParameterName="p2".../>
          </CombinerParameters>
