Subject: RE: [xacml] xpath reference is possibly outdated

It is likely that Xpath/Xquery documents will go to candidate recommendation later this year, and to the W3C recommendation status next spring.  When that happens, we should revisit our Xquery/Xpath data model to XACML data model binding.


There have been several iterations of the F&O spec since 2002 – it was not and is not a good idea to try to track a working draft from a stable document.   We are just borrowing a definition from the 2002 spec.

Subject: [xacml] xpath reference is possibly outdated



in xacml 2.0 spec in "A3.15 XPath-based functions" we have:

4915 • urn:oasis:names:tc:xacml:1.0:function:xpath-node-equal
4916 This function SHALL take two "http://www.w3.org/2001/XMLSchema#string" arguments,
4917 which SHALL be interpreted as XPath expressions, and SHALL return an
4918 "http://www.w3.org/2001/XMLSchema#boolean". The function SHALL return "True" if any
4919 of the XML nodes in the node-set matched by the first argument equals, according to the
4920 "op:node-equal" function [XF Section 13.1.6], any of the XML nodes in the node-set
4921 matched by the second argument.

,where XF refers to:
3973 [XF] XQuery 1.0 and XPath 2.0 Functions and Operators, W3C Working Draft
3974 16 August 2002. Available at: http://www.w3.org/TR/2002/WD-xquery
3975 operators-20020816

First of all, there's a fresh version of the document, http://www.w3.org/TR/2005/WD-xpath-functions-20050915. It's dates as of Sep 15 2005. Second, there's no "op:node-equal" function in the current XF document.
