Subject: [xacml-comment] About the Syntax and Semantics of <AttributeAssignment>
Hi, I've just found an <AttributeAssignment> element has three kinds of child elements in Section 4.2.4.3 (Rule 3) [095] <AttributeAssignment AttributeId= [096] "urn:oasis:names:tc:xacml:1.0:example:attribute:mailto" [097] DataType="http://www.w3.org/2001/XMLSchema#string"> [098] <AttributeSelector RequestContextPath= [099] "//md:/record/md:patient/md:patientContact/md:email" [100] DataType="http://www.w3.org/2001/XMLSchema#string"/> [101] </AttributeAssignment> In this case, <AttributeSelector> is used to specify the content of the attribute assignment. It seems to me that the semantics is not defined anywhere. Section 5.36 should define it. [102] <AttributeAssignment AttributeId= [103] "urn:oasis:names:tc:xacml:1.0:example:attribute:text" [104] DataType="http://www.w3.org/2001/XMLSchema#string"> [105] <AttributeValue> [106] Your medical record has been accessed by: [107] </AttributeValue> [108] </AttributeAssignment> In this case, <AttributeValue> is used to specify the content of the attribute assignment. Again, Section 5.36 should define the semantics. Also, is the syntax of this <AttributeValue> element the same as defined in the XACML schema, i.e., <xs:element name="AttributeValue" type="xacml:AttributeValueType"/> ??? If yes, the DataType attribute must be added (because it is REQUIRED). [109] <AttributeAssignment AttributeId= [110] "urn:oasis:names:tc:xacml:example:attribute:text" [111] DataType="http://www.w3.org/2001/XMLSchema#string"> [112] <SubjectAttributeDesignator AttributeId= [113] "urn:osasis:names:tc:xacml:1.0:subject:subject-id" DataType="http://www.w3.org/2001/XMLSchema#string"/> [114] </AttributeAssignment> In this case, <AttributeDesignator> is used to specify the content of the attribute assignment. Again, Section 5.36 should define the semantics. Satoshi Hada IBM Tokyo Research Laboratory mailto:satoshih@jp.ibm.com
