 IDTrust Call for Papers
  http://middleware.internet2.edu/idtrust/2011/

 Test Cases, V2, V3
  Rich raised the question of where the v2 schemas are for the test 
  cases in the subversion repository. Discussion moved to the list.

 PCAST
  David reviewed recent work by the President's Council of Advisors on
  Science and Technology (PCAST). A document was posted to the TC list.

III. Issues

 BTG
  Postponed since David was not on call.

 Attribute Assertions in XACML request
  Gregory discussed the concept of introducing an new DataType,
  AttributeID and FunctionId. This is described in a note posted to the
  TC list (immediately prior to the call). Predicates are not limited
  to simple comparisons, rather any/all XACML functions could be used
  within the predicate. 

  Erik noted that this approach tightly binds knowledge of the Request
  with the Policy composition, so what are the benefits over attributes.
  Gregory offered that this approach would require no modification of 
  the Context Handler. Further discussion has been directed to the list.

 PIP directive
  Hal briefly reviewed the philosophy of knowing all necessary
  information in advance by being able to gather information various
  sources as necessary. Rich noted that he believes that the
  specification is underspecified in this area as callbacks are
  inferred only in non-normative text and that this should be
  normatively defined. Hal discussed work on AMF that is being done in
  this area.

meeting adjourned.
