Native policies can be supported by TOSCA policy type and policy. As for native Drools policy, since native DRL is packaged in JAR which has been deployed to nexus repo along with other dependency JARs, TOSCA policy for native DRL only needs to include the pointer for native JAR as well as necessary information being used by Drools PDP to instantiate a new controller instance with native DRL loaded into memory. Corresponding policy type should be defined and pre-loaded into policy framework so that TOSCA policy for native policy type can then be created off. As for native XACML policy, its contents are basically encoded in XML which is all XACML PDP needs to load into engine and run. Thus, TOSCA policy for native XACML only needs to include this XML content. An URL-encoded string can be created off composed XACML XML and is populated to a string property.
