As an A&AI developer, I need to create a named-query.  Accoring to cgao of the policy team, elements to connect are: source vnf-id, related service-instance-id, all related vnfs in this service-instance-id (vnf should have "generic-vnf.vnf-id" and "model-invariant-id")
 
Investigate using a secondary-filter on the request to post-process the results that are returned by model-invariant-id.
