Union of http://hl7.org/fhir/us/core/StructureDefinition/us-core-observation-lab and http://hl7.org/fhir/us/vrdr/StructureDefinition/vrdr-cause-of-death-part1

This is the set of resources that conform to either of the profiles US Core Laboratory Result Observation Profile (http://hl7.org/fhir/us/core/StructureDefinition/us-core-observation-lab) and Cause Of Death Part 1 (http://hl7.org/fhir/us/vrdr/StructureDefinition/vrdr-cause-of-death-part1). E.g. what you have to deal with if you get resources conforming to one of them
