Union of http://hl7.org/fhir/us/core/StructureDefinition/us-core-simple-observation and http://hl7.org/fhir/us/mdi/StructureDefinition/Observation-mdi-cause-of-death-part1

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