org.glite.authz.pap.common.xacml.impl.PolicySetTypeString
This class provides an implementation for the {@link PolicySetType} interface. Theimplementation, which is based on the one provided by OpenSAML, adds the facility to store the PolicySet as a string in order to cut on memory usage.
The following methods does not need to build the DOM: {@link #getPolicySetId()}, {@link #getPolicySetString()}.
All the other methods build the DOM object.
In order to release the memory an holding just the string and the id use the utility method {@link TypeStringUtils#releaseUnneededMemory(Object)}.

                    XACMLPolicyStatementType policyStatement = (XACMLPolicyStatementType) statement;


                    for (PolicySetType policySet : policyStatement.getPolicySets()) {
                        responseList.add(new PolicySetTypeString(policySet));
                    }
                    for (PolicyType policy : policyStatement.getPolicies()) {
                        responseList.add(new PolicyTypeString(policy));
                    }
