The procedure for administrative request generation in Section 4.5 of the XACML v3.0 Administration and Delegation Profile Version 1.0 Committee Specification 01 does not account for the category URI in XPathCategory XML attributes. In order to ensure the correct evaluation of any attribute selectors or XPath functions in administrative policies, attribute values of the xpathExpression data-type should have their XPathCategory XML attribute mapped. If the XPathCategory URI value refers to a Category that is mapped according to step 1.d., then that URI value should be prefixed with "urn:oasis:names:tc:xacml:3.0:attribute-category:delegated:". This only looks to be necessary for attribute values within <Attributes> elements that are mapped according to 1.d. (so the contents are not identical anymore). The <Attributes> elements in 1.a. and 1.c. disappear and the XPathCategory attributes within the <Attributes> element in 1.b. would have been mapped previously.
Any XPathCategory XML attributes within the <Attributes> element in step 2 must also have their values mapped. Regards, Steven
With regard to my earlier message about the problem of concatenating a URN and a URI, solution (3) would entail adding an XPathCategoryPrefix XML attribute alongside the XPathCategory attribute. Regards, Steven
