Subject: [xacml-comment] INCOMPLETE: behavior when XPath encountered,but not supported
The behavior of a PDP that does not support the optional XPath *Defaults, selectors, functions, etc. when presented with a policy containing such elements is not specified. In some cases, the XPath elements may appear in a <Target> element, making it impossible to determine whether or not a PolicySet, Policy, or Rule is applicable. In other cases, the <Target> element may not require any XPath functionality, and a PolicySet, Policy, or Rule may be applicable, but evaluating the <Condition> in the Rule may require XPath functionality. Possible behavior: If, during evaluation of a Request, any unsupported element is encountered, then the PDP MUST return a result of Indeterminate. Anne Anderson -- Anne H.
