NOTE: The native policy type is already loaded in policy framework during installation, hence a user can directly deploy native policies in respective pdp engines without a need to create policy type first.
3. PAP Enhancements
PDP Engines must now register with PAP Groups must be provisioned to support the new policy types for native policies they support in order for policies to be deployed by PAP to the PDP's. This will require an additional entry to be added into supported policy types list to indicate which native policy type each specific PDP engine can support.
3.1 Example of PDP Register
Only change needed is to add a new supported policy type to PDP status message when it registers itself with PAP. For XACML PDP, new policy type "onap.policies.controlloop.native.Xacml" should be added. Likewise, new policy type "onap.policies.controlloop.native.Drools" should be added when Drools PDP registers itself with PAP. For example

3.2 Example PDP Group Deploy
policy types list to indicate which native policy type each specific PDP Subgroup can support.
3.1 PDP Group & SubGroup
The Like PDP registration message, the same native policy type should be added into supported policy types list to indicate which type of native policies each pdpSubGroup PDP SubGroup can support.
Below is one example to deploy a PDP groupof PDP Group with native policies support for xacml, drools & apex engines.

2 Deploy/Undeploy API
No change is envisioned on current deploy/undeploy API. Still, only policy-id and version are needed to tell PAP to deploy/undeploy a native policy.
...
Apex PDP already supports the native policies created using the policy type defined in section 2.3.1 above.NOTE: The native policy type is already loaded in policy framework during installation, hence a user can directly deploy native policies in respective pdp engines without a need to create policy type first.
5. Sequence flows for native policy design, deployment and enforcement
