    This is fine.
    So all <xacml-context:Attribute> elements must have
    exactly one <xacml-context:AttributeValue> element.
    
    >>- 3.15 Semantics of the <<AttributeDesignator> with

    Because of the approval of 3.14,
    this unclear point will disappear.
    That is, the semantics of mustBePresent is
    already clear enough from
    Section 5.29, line 2313
    Section 5.30, line 2338
    Section 5.31, line 2364
    Section 7.9.2, line 2982
    
    If(attribute values are present)
      return the bag of the attribute values.
    else
      if(mustBePresent==true)
        return Indeterminate
      else
        return an empty bag
    
    So 3.15 can be removed from the errata list.

    Minutes of OASIS XACML Focus Group
    05 June 2003
    
    Present: Anne Anderson (scribe), Ed Coyne (SAIC, prospective),
    Michiharu Kudo, Simon Godik, Carlisle Adams, Steve Crocker
    
    Agenda
    ======
    Review Errata
    
    1. Work Item G: Environment in Target
    
       [Lower priority for today than Errata.  We returned to this
       after discussing Errata.]
    
       Michiharu asked about why this was dropped from the 1.1 Work
       Item list at the last meeting.  Michiharu disagrees with
       dropping this, but he is not clear on when something is not
       appropriate for 1.1 (Hal's comment about why this item should
       be dropped from the 1.1 Work Items).
    
       RECOMMENDATION: All requirements for including this in 1.1
       have been met with the exception of agreeing on a solution by
       the end of June 2003.  Michiharu has followed the agreed upon
       process of submitting a proposal by a certain date, a detailed
       solution by a certain date, etc.
    
       Simon has an alternative proposal/solution for this that he
       will submit to the e-mail list for discussion.
    
    2. Simon still having problems downloading the specification.
    
       Michiharu has checked with OASIS webmaster, who is aware of
       the problem since webmaster has same problem.
    
       Michiharu will put a note on the XACML TC web site saying
       there may be a problem with some browsers.
    
    3. Errata review
    
       Simon published draft-xacml-errata-02.doc attached to
       http://lists.oasis-open.org/archives/xacml/200306/msg00001.html
    
    - 3.12 <Status> element MAY: include action and environment
      attributes.
    
      RECOMMENDATION: Approve
    
    - 3.13 <Status> element MUST NOT list action or environment
      attributes.
    
      RECOMMENDATION: Approve
    
    - 3.14 <AttributeValue> occurrence is inconsistent.
    
      RECOMMENDATION: Approve.
      Also remove minOccurs="0" from line 2644 in spec to agree with
      schema.
    
    - 3.15 Semantics of the <<AttributeDesignator> with MustBePresent
      attribute set to "true" is unclear when <Attribute> does not
      contain <AttributeValue>
    
    **RECOMMENDATION: Needs more thought.  Might approve, except
      change text to say "result is not an empty bag, but one empty
      element that is added to the resulting bag."  But in the case
      of an empty <AttributeValue DataType="...#integer">, then the
      <AttributeValue> is schema-invalid.
    
    - 3.16 MustBePresent attribute semantics for the
      <AttributeSelector> element.
    
      RECOMMENDATION: Approve.  Use status of "processing-error", not
      "missing-attribute" in the place where a question mark occurs.
    
    - 3.17 Unclear how to convert nodes from XPath expression into
      bag of attributes.
    
    **RECOMMENDATION: TBD.  [XF] defines how to convert nodes into
      LITERAL, but the processing is very complex.  Michiharu will
      investigate a solution.
    
    Other items in the errata list have probably already been
    disposed, but Simon has not yet found the relevant e-mails.
    
    - 3.7 Obligations for the policy.
    
    **RECOMMENDATION: Anne to look for e-mails where Polar? clarified
      to Satoshi that 7.11 refers to both <Policy> and <PolicySet>
      and then Satoshi said 7.11 was clear with that clarification,
      and so Erratum 3.7 could be dropped.
    
    - 3.9 <XPathVersion> element
    
    **RECOMMENDATION: Simon will look for discussion of this on the
      list.  No one can remember what the disposition was.
    
    - Several new errata reported to Michiharu by Jim Fuller, but not
      put on xacml-comment.  Michiharu will forward to xacml-comment.
