- The Policy Framework loops over the root PolicyType to the last descendant PolicyType
- A check of the Policy Type specification is made to see if targets have been specified on it, if so, the XACML PDP is invoked with the specified target policy and the specified targets as parameters (Step 2).
- If the target policy for the Policy Type rejects the targets, execution of the policy proper is rejected (Step 3).
- If no targets are specified on the Policy Type or the target policy for the Policy Type accepts the target, execution continues
