## Union of http://hl7.org/fhir/us/davinci-cdex/StructureDefinition/cdex-signature and http://hl7.org/fhir/us/davinci-cdex/StructureDefinition/cdex-signature

This is the set of resources that conform to either of the profiles CDex Signature Profile (http://hl7.org/fhir/us/davinci-cdex/StructureDefinition/cdex-signature) and CDex Signature Profile (http://hl7.org/fhir/us/davinci-cdex/StructureDefinition/cdex-signature). E.g. what you have to deal with if you get resources conforming to one of them
