Subject: FW: XACML Charter Scope
-----Original Message----- From: Simon Y. Blackwell Sent: Wednesday, May 23, 2001 2:03 AM To: 'Hal Lockhart' Subject: RE: XACML Charter Scope Given that I actually dreamt about this issue tonight and am now up thinking about it (boy am I sick ;-), suffice it to say that I concur with Hal. I do think it should be possible to use existing protocols to query an XACML repository and exchange messages. SAML should certainly play a role here. My guess is XPath or XQuery might also. > -----Original Message----- > From: Hal Lockhart [mailto:hal.lockhart@entegrity.com] > Sent: Monday, May 21, 2001 12:48 PM > To: 'xacml@lists.oasis-open.org' > Subject: XACML Charter Scope > > > I observed on the concall today that the proposed charter > says the purpose > "is to define a core schema and corresponding namespace."
