SAML claims with picketlink

[abhishekhp]

How to get hold of claims in picketlink that do not have an attribute name of 'role' ? Also how can the JAAS subject and principal be obtaines from with in an web service context ?

						<AttributeStatement>
							<Attribute
								Name="http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name">
								<AttributeValue>NICNAME</AttributeValue>
							</Attribute>
							<Attribute
								Name="http://schemas.xmlsoap.org/ws/2005/05/identity/claims/givenname">
								<AttributeValue>GIVENNAME</AttributeValue>
							</Attribute>
						</AttributeStatement>

How do i get a  handle to the above attributes using picketlink API JAAS context. It appears JAAS modules just looks for an attribute of name ROLE as a child element of <AttributeStatement>
