Topic: Reference to non-fhir entity/resource

In many resources, there is a subject attribute that allows adding a reference to another resource (often to describe what the resource is "about".) Is this attribute usable for entities that are not resolvable to a FHIR resource? For example, we have a system that houses protocol information that has no FHIR capabilities, but I want to reference things in this system. Could I use the following, even though "ABCD-123" isn't a FHIR resource?

"subject": {
    "type": "ResearchStudy",
    "reference": "ResearchStudy/ABCD-123",
    "identifier": {
        "system": "ProtocolSystem",
        "value": "urn:uuid:0c3151bd-1cbf-4d64-b04d-cd9187a4c6e0"
    },
    "display": "Protocol ABCD-123"
  },

In that case you fill out the reference.identifier alone, don't fill out the reference.reference unless it is a FHIR resource id. Your is the reason that the datatype Reference was updated at STU3
