[sunxacml-discuss] SubjectAttributeDesignator question

[Lanz, D. <dl...@mi...>]

How does one programmatically access the xml attributes of the
SubjectAttributeDesignator element?  The SubjectAttributeDesignator is
a subelement of the SubjectMatch element in an xacml policy target, as
shown in the policy fragment below:
 	=20
 	  <Target>
 	    <Subjects>
 	      <Subject>
 	        <SubjectMatch
 MatchId=3D"urn:oasis:names:tc:xacml:1.0:function:string-equal">
 	          <AttributeValue=20
 	            DataType=3Dhttp://www.w3.org/2001/XMLSchema#string
 	              >employee</AttributeValue>
 	          <SubjectAttributeDesignator=20
 	            AttributeId=3D"group"=20
 DataType=3D"http://www.w3.org/2001/XMLSchema#string"/>
 	        </SubjectMatch>
 	      </Subject>
 	      ...
 	   </Target>
 	=20
The subject attribute value is available from an EvaluationCtx by
calling (as an example):
 	  getSubjectAttribute(new
URI(com.sun.xacml.attr.X500NameAttribute.identifier), new
URI("urn:oasis:names:tc:xacml:1.0:subject:subject-id"), new
URI("urn:oasis:names:tc:xacml:1.0:subject-category:access-subject"))

But, it's not evident how to access the SubjectAttributeDesignator.
