Change Request: In context-16f.xsd, the AttributeValue element does not have a DataType xml attribute. I request that this be added. Rationale: In splitting SAML subject identifier information into XACML attributes, we decided that we did not need a subject-id-format attribute since the subject identifier name format could be expressed using the DataType xml attribute on the subject-id attribute. Since the current context schema does not have a DataType xml attribute in AttributeValue, this decision can not be implemented. If this change request is not granted, we need to choose an identifier for subject-id-format [I suggest BASE:subject-id-format]. However, I much prefer having DataType added to the AttributeValue element since this allows a natural association of the format (DataType) with its value. Daniel suggested that PDPs may wish to interpret context data as strings. Supplying a DataType attribute does not prevent this. Current text in draft-xacml-schema-context-16f.xsd: <xs:element name="AttributeValue" type="xs:anyType"/> Requested changed text: <xs:element name="AttributeValue" type="xacml:AttributeValueType"/> [NOTE following from policy-16f.xsd: <xs:complexType name="AttributeValueType"> <xs:complexContent> <xs:extension base="xs:anyType"> <xs:attribute name="DataType" type="xs:anyURI" use="required"/> </xs:extension> </xs:complexContent> </xs:complexType> END NOTE] Anne Anderson -- Anne H.
