Subject: [xacml] Text change request
The following are the text change requests. [1] AttributeSelector, Page 49 <AttributeSelector> [required] MAY be used to identify one or more values in the <Subject> element of <xacml-context:Request> element. It MUST contain a legal xpath expression over the <Subject> element of the <xacml-context:Request> element. ==> <AttributeSelector> [optional] Attribute selector using XPath expression. It MUST contain a legal xpath expression over the <xacml-context:Request> element. This operator returns a bag of string data or a single primitive value. In case of XPath 1.0, an evaluation value of the XPath expression is either a node set, string value, numeric value, and boolean value. When node set is returned, each node may consist of children nodes (structured node). Then each node is converted into a string data by applying a string function defined in XPath 1.0 specification. Then this operator returns a bag of string values. When either string, numeric or boolean value is returned, this operator returns a single primitive value of xs:string, xs:decimal, and xs:boolean type, respectively. When this element is specified, the policy MUST define the version of the XPath specification using <XPathVersion> element. When an xpath expression has one or more namespace prefix, they are resolved using XPath namespace and prefix information specified in the <XPathNamespace> element below this operator. If no such element is specified, then an <XPathNamespace> element in <PolicyDefaults> element in the parent <Policy> (or <PolicySet>) element is used. [2] The latest draft and schema does not reflect the change request 0032 (Schema change of AttributeSelector) [3] XPathVersion, Page 50 In the example, XPathVersion is used but in the text, XpathVersion is used. It should be XPathVersion. Michiharu Kudo IBM Tokyo Research Laboratory, Internet Technology Tel. +81 (46) 215-4642 Fax +81 (46) 273-7428
