Dear Jeff, Thank you for the erratum. I have forwarded it to the xacml-comment mailing list. I assume, by "resource label", you mean a classification scheme and a classification value, such as "U.S. Navy Classification System XYZ" "top secret". This could be expressed in XACML as an "Attribute" of the Resource. The AttributeId could be a URN indicating the classification scheme, and the AttributeValue could be the classification value. Does this satisfy your requirements?

Resource labels are part of the authorization support in the X.509 standard and are used in several RBAC implementations. Resource labels are useful in enabling resource characteristics (i) to be set on resources and (ii) to form part of access control decisions. I feel sure that you must be aware of this and can only conclude that a PolicySet is intended to act as a resource label (in addition to acting as a policy set!). Is this correct? > > > Warmest regards, > > Jeff Lawson > Cogent Logic > Toronto, Canada > (416) 340 8025 > > > >
