  v: **Australian adaptation of the [HL7 International CDA EntryRelationship class]( https://hl7.org/cda/stds/core/2.0.1-sd/StructureDefinition-EntryRelationship.html)**. This is a generated StructureDefinition that describes CDA - that is, CDA as it actually is for R2. The intent of this StructureDefinition is to enable CDA to be a FHIR resource. That enables the FHIR infrastructure - API, conformance, query - to be used directly against CDA
