I would like to use the attributeselector feature in JBossPDP.
see http://docs.oasis-open.org/xacml/2.0/access_control-xacml-2.0-core-spec-os.pdf (chapter 5.42)
Although the attributeselector feature is optional, it would be cool if
jboss xacml could support it in future. (as far as I know Sun xacml supports it).
No special configuration is needed. It is provided to you by default.
