-	 * 
-	 * 	policy - Expect a properties file that contains updated lists of the root and referenced policies that the PDP should

-	 * 
-	 * 		Specifically should AT LEAST contain the following properties:
-	 * 		xacml.rootPolicies
-	 * 		xacml.referencedPolicies
-	 * 
-	 * 		In addition, any relevant information needed by the PDP to load or retrieve the policies to store in its cache.
-	 *
-	 * 		EXAMPLE:
-	 *	 		xacml.rootPolicies=PolicyA.1, PolicyB.1
-	 *
-	 *			PolicyA.1.url=http://localhost:9090/PAP?id=b2d7b86d-d8f1-4adf-ba9d-b68b2a90bee1&version=1
