 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.

 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.
