If you change the wd and it gets voted to csd, that is all that is required by OASIS. The usual procedure for a change of this kind is to inquire on the list and/or on a call if anyone objects. > .

My reading of the 3.0 core spec is that XPathCategory specifies where in the Request to obtain the text, not the category of the attribute value thus obtained. Any <Attributes> element can contain a <Content> element, so you need to know which one to apply the XPath expression to. I believe this is a consequence a change from 2.0. In 2.0 selectors could pretty much point at anything. In 3.0 they (and attributes of type XPath) can only point to <Content> elements in the Request, but it does not have to be from the same Category. Erik, did I get this right? > .

Appendix B.8 says: ---- This identifier indicates that some attribute value contained a syntax error, such as a letter in a numeric field. urn:oasis:names:tc:xacml:1.0:status:syntax-error ---- Hal > Thanks, > David.
