what about my presented solution, like what are your comments ?

<Apply FunctionId="SECTINO: Extract-parameter-from-request">
        <AttributeValue  ="http://www.w3.org/2001/XMLSchema#string";>
                /Request/Action/Attribute[@AttributeID="p"]/AttributeValue/p/ID
        </AttributeValue>
</Apply>



in response the the request
<Request>
..
..
<Action>
<Attribute AttributeId="urn:oasis:names:tc:xacml:1.0:attribute:p"
                DataType="http://www.w3.org/2001/XMLSchema#String";>
 <AttributeValue  DataType="http://www.w3.org/2001/XMLSchema#String";>
   &lt;p&gt;
    &lt;iD&gt;127Asbc &lt;/iD&gt;
    .
    &lt;/p&gt;
   </AttributeValue>
     </Attribute>
</Action>
.
.
</Request>

since it deals with not only single values, but mixed contents agreed??
what are the discrepencies in your opinion as you are the author of 
sun-xacml implemenation, is this makes any conflict with your implemenations 
functions by the way ???
