Subject: Hierarchical resource profile of XACML v2.0
Hi Guys, Reading the Hierarchical resource profile of XACML v2.0, I am a little puzzled by "3.1 Nodes in an XML document" requiring that not only should one include a resource-id of type xpath-expression for the node that is the resource for the access decision but also it parent and all ancestors. Why is this required by the spec? Why is it necessary. Should an impl of a PDP not simply be able to traverse the parent and ancestors of the node using normal XML processing and node traversal mechanism in teh various xml processing tools and apis? I must be missing something obvious. Thanks for any explanation. -- Regards, Farrukh Web: http://www.wellfleetsoftware.com
