The translator then uses those "matchable" properties to translate a policy into a XACML OASIS 3.0 policy which allows for fine-grained decision making such that ONAP applications can retrieve the appropriate policy(s) to be enforced during runtime.

+Match Policy Type
+=================
+
+This Policy type can be used to design your own Policy Type and utilize the :ref:`StdMatchableTranslator <xacml-matchable-label>`, and does not need to build your own custom application. You can design your Policy Type by inheriting from the Match policy type (eg. onap.policies.match.<YourPolicyType>) and adding a **matchable** metadata set to **true** for the properties that you would like to request a Decision on. All a user would need to do is then use the Policy Lifecycle API to add their Policy Type and then create policies from it. Then deploy those policies to the XACML PDP and they would be able to get Decisions without customizing their ONAP installation.

+This is an example Decision API request that can be made:
