## Union of http://hl7.org/fhir/us/core/StructureDefinition/us-core-medicationrequest and http://hl7.org/fhir/us/uds-plus/StructureDefinition/uds-plus-medicationrequest

This is the set of resources that conform to either of the profiles US Core MedicationRequest Profile (http://hl7.org/fhir/us/core/StructureDefinition/us-core-medicationrequest) and De-Identified UDS Plus MedicationRequest (http://hl7.org/fhir/us/uds-plus/StructureDefinition/uds-plus-medicationrequest). E.g. what you have to deal with if you get resources conforming to one of them
