Title: RE: [xacml] XACML Request as "notional" XML document Anne - Thanks for taking the trouble to consult Eve. My reading is that she identifies one potential problem that (I believe) will not apply in our case. The "transformer" that transforms saml to xacmlContext will start a session with the PDP, in which it requests a decision. Any subsequent requests for attributes by the PDP will be in that session. Therefore, the transformer will be able to relate those attribute requests to its decision request. Changing the name from request context to query context would be fairly simple. All the best. Tim PSS. I am tryingg out a new keyboard. SO, I apoliose for the porr tyoings. ----------------------------------------- Tim Moses Tel: 613.270.3183
