ONAP Supported Policy Types
***************************
-In ONAP the following Policy Types are supported. Each Policy Type is implemented as an application that extends the **XacmlApplicationServiceProvider**. For details on each implementation, please refer to the `applications submodule of the onap/xacml-pdp project <https://gerrit.onap.org/r/gitweb?p=policy/xacml-pdp.git;a=tree;f=applications;h=047878fe14851d8a51998e065b8aca583ed8c994;hb=refs/heads/dublin>`__.

By cloning the policy/xacml-pdp repository, one can run the JUnit tests to get a better understanding on how applications are built using translators and the XACML Policies that are generated for each Policy Type. Each application supports one or more Policy Types and an associated "action" used by the Decision API when making these calls.

Guard Policy Types
==================
-These Policy Types are used by Control Loop Drools Engine to support guarding of Control Loops during runtime control loop execution. NOTE: For Dublin, these policy types are not TOSCA compliant but rather a simple variation of the Casablanca legacy guard policy.

The same Decision API payload example for guard applies to this Policy Type.
Optimization Policy Types
=========================
-These Policy Types are used by the OOF Project support placement in ONAP. The OOF Platform makes a call to the Decision API to request these Policies based on the values specified in the **policyScope** and **policyType** properties. Please refer to the OOF Project for more details on how these Policy Types are using in their platform.
+These Policy Types are designed to be used by the OOF Project support placement in ONAP. The OOF Platform makes a call to the Decision API to request these Policies based on the values specified in the onap.policies.Optimization properties that have a metadata property called "matchable" and its value is set to "true". NOTE: For El Alto, this is dark code and OOF has not yet upgraded to the new Decision API to support this. Please refer to the OOF Project for more details on how it currently uses the Legacy API and policy models in their platform.

+Native XACML Policy Type
+=======================
+This Policy type is used by any client or ONAP component who has the need of native XACML evaluation. A native XACML policy or policy set encoded in XML can be created off this policy type and loaded into the XACML PDP engine by invoking the PAP policy deployment API. Native XACML requests encoded in either JSON or XML can be sent to the XACML PDP engine for evaluation by invoking the native decision API. Native XACML responses will be returned upon evaluating the requests against the matching XACML policies. Those native XACML policies, policy sets, requests and responses all follow the `OASIS XACML 3.0 Standard <https://www.oasis-open.org/committees/tc_home.php?wg_abbrev=xacml>`__.

+According to the XACML 3.0 specification, two content-types are supported and used to present the native requests/responses. They are formally defined as "application/xacml+json" and "application/xacml+xml".

Supporting Custom Policy Types
******************************
-In order to support your own custom Policy Type that the XACML PDP Engine can support, one needs to build a Java service application that extends the **XacmlApplicationServiceProvider** interface and expose it in the classpath used to load the XACML PDP Engine. First, ensure you define and create the TOSCA Policy Type according to these :ref:`Policy Design and Development <design-label>`. You should be able to load your custom Policy Type using the :ref:`Policy Lifecycle API <api-label>`. Once successful, you should be able to start creating policies from your custom Policy Type.

-See each of the ONAP Policy Type application implementations for examples on how to implement the methods for the **XacmlApplicationServiceProvider**. Consider re-using the standard implementations.
+Once your application is developed and the ONAP XACML PDP Engine can find your application via setting the classpath appropriately, then use the :ref:`PAP REST API <pap-label>` to ensure the ONAP XACML PDP is registering your custom Policy Type with the PAP. Once successful, then you should be able to start deploying the created policies to the XACML PDP Engine.
