Change .agent.net to a network [x] of type URI or Reference(Endpoint) agent.network [x] 0..1        When a network is used, indicate the endpoint used by the agent     networkReference  Reference(Endpoint) endpoint defined in Endpoint resource     networkUri             uri                              endpoint in terms of a URI / URL     networkAddress     string                         endpoint when address / name is all that is known Definition: The endpoint used by this agent. Requirement: When a network protocol is used the endpoint is associated with the agent most directly using the endpoint. This is usually the software agent that has implemented the application level protocol.  Preference is to define network in terns of a Reference(Endpoint), or URI; use address only when address or hostname is known. Comment: When remote network endpoint is known, another agent representing the remote agent would indicate the remote network endpoint used. Convention is to indicate data flowing from Source to Destination. The convention for Search, given data flows both ways (query parameters vs results), is to have the Source as the initiator of the Search Transaction, and the Destination the responder to the Search transaction.
