In order to use a XACML policy for authorization in WSO2 Identity Server, you need to publish it to the Policy Decision Point (PDP) where the authorization decision is made. The policy will not be enforced unless it is published.

At the point of publishing the policy, the policy in the Policy Administration Point(PAP) policy store will sync up with PDP policy store. The PDP will access one or more policies in the Policy Administration Point(PAP), and other additional information such as subject, resource, action and environmental resources in the Policy Information Point(PIP) to make the decision. For more information about this process, see XACML system architecture. 

You can publish a XACML policy to PDP for runtime evaluation using the instructions in this topic.
