XACML Subject, Action, Resource and Environment should use List rather than Set
-------------------------------------------------------------------------------

                 Key: SECURITY-523
                 URL: https://jira.jboss.org/browse/SECURITY-523
             Project: PicketBox (JBoss Security and Identity Management)
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: jboss-sunxacml
            Reporter: Anil Saldhana
            Assignee: Anil Saldhana


List can hold duplicates where as set cannot.

XACML spec has the bag functionality such as the following request:

===============
<?xml version="1.0" encoding="UTF-8"?>
<Request  
    xmlns="urn:oasis:names:tc:xacml:2.0:context:schema:os" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation=" urn:oasis:names:tc:xacml:2.0:context:schema:os 
      http://docs.oasis-open.org/xacml/access_control-xacml-2.0-context-schema-os.xsd">
    <Subject>
        <Attribute
              AttributeId="urn:oasis:names:tc:xacml:1.0:subject:subject-id"
              DataType="http://www.w3.org/2001/XMLSchema#string">
            <AttributeValue>Julius Hibbert</AttributeValue>
        </Attribute>
        <Attribute
              AttributeId="urn:oasis:names:tc:xacml:1.0:conformance-test:test-attr"
              DataType="http://www.w3.org/2001/XMLSchema#string">
            <AttributeValue
                  DataType="http://www.w3.org/2001/XMLSchema#string">   This  is IT!  </AttributeValue>
        </Attribute>
        <Attribute
              AttributeId="urn:oasis:names:tc:xacml:1.0:conformance-test:test-attr"
              DataType="http://www.w3.org/2001/XMLSchema#string">
            <AttributeValue
                  DataType="http://www.w3.org/2001/XMLSchema#string">   This  is IT!  </AttributeValue>
        </Attribute>
    </Subject>
    <Resource>
        <Attribute
              AttributeId="urn:oasis:names:tc:xacml:1.0:resource:resource-id"
              DataType="http://www.w3.org/2001/XMLSchema#anyURI">
            <AttributeValue>http://medico.com/record/patient/BartSimpson</AttributeValue>
        </Attribute>
    </Resource>
    <Action>
        <Attribute
              AttributeId="urn:oasis:names:tc:xacml:1.0:action:action-id"
              DataType="http://www.w3.org/2001/XMLSchema#string">
            <AttributeValue>read</AttributeValue>
        </Attribute>
    </Action>
</Request>
=================

So if you add hashcode/equals as in SECURITY-522,  you will see that the subject attributes will not be 3 but rather just 2.
