Union of http://hl7.org/fhir/us/vr-common-library/StructureDefinition/Observation-usual-work-vr and http://hl7.org/fhir/us/vr-common-library/StructureDefinition/Observation-usual-work-vr

This is the set of resources that conform to either of the profiles Observation - Usual Work (http://hl7.org/fhir/us/vr-common-library/StructureDefinition/Observation-usual-work-vr) and Observation - Usual Work (http://hl7.org/fhir/us/vr-common-library/StructureDefinition/Observation-usual-work-vr). E.g. what you have to deal with if you get resources conforming to one of them
