   were approved unanimously.

   12 May:

2. Deontic logic and generalization of XACML results

   Tim Moses posted results of his review of the applicability of
   constructs from deontic logic to the XACML result
   generalization work at:


   Tim's conclusion was that the deontic concepts of obligation
   and prohibition were what XACML is already doing and that
   nothing new.

   Polar noted that deontic logic actually consists of variations
   on just "obligation"

   "Prohibition" means an obligation to deny.
   "Dispensation" means there is not an obligation to deny.

   Bill noted that this arose from the F2F discussion of
   differences between imperatives that must be performed in
   conjunction with access, and obligations that must be done
   eventually or in parallel, but not necessarily part of the
   granting of access itself.

3. Document on differences between V1.0, V1.1, and V2.0

   Bill wrote a simple document that has been posted to the list at
http://lists.oasis-open.org/archives/xacml/200505/msg00023.html and is
also linked form the TC home page under "Working Drafts".  Although he
was working on a more detailed document, this simple overview of the
changes is something we could put on our web page right now.

   ACTION: All members to review and comment.  Will be voted for
   approval at a subsequent TC meeting.

4. Executive summary of XACML

   SAML has an executive summary document, and a document like
   this might be helpful for potential XACML users.  There was
   agreement that such a document would be useful, but no one is
   currently able to take on authoring such a document.

   Volunteers for editing such a document are encouraged to step

5. Major areas of ongoing work

   a. Tim's generalization proposal

   Tim was not on the call, so we did not discuss this.

   b. Erik's delegation proposal

   Erik has received permission to serve as editor, has just
   finished his prior obligations, and will be starting work on
   the delegation spec next week.

   c. Bill proposed need for a work items list.  Erik proposed
   using his open issues list.  Bill suggested adding who is
   responsible, expected completion date, simple status on what
   has been closed.

   Erik will publish a first draft over the weekend.  The draft
   can stimulate conversation about who is responsible, etc.

The meeting adjourned at 10:22am EDT.
