This is the set of resources that conform to either of the profiles US Core Smoking Status Observation Profile (http://hl7.org/fhir/us/core/StructureDefinition/us-core-smokingstatus) and ADI Upon Death Preferences (http://hl7.org/fhir/us/pacio-adi/StructureDefinition/ADI-UponDeathPreferences). E.g. what you have to deal with if you get resources conforming to one of them
