## Intersection of http://hl7.org/fhir/us/core/StructureDefinition/us-core-simple-observation and http://hl7.org/fhir/us/vrdr/StructureDefinition/vrdr-decedent-usual-work

This is the set of resources that conform to both US Core Simple Observation Profile (http://hl7.org/fhir/us/core/StructureDefinition/us-core-simple-observation) and Decedent Usual Work (http://hl7.org/fhir/us/vrdr/StructureDefinition/vrdr-decedent-usual-work).
