Union of http://fhir.org/guides/hrsa/uds-plus/StructureDefinition/uds-plus-observation and http://fhir.org/guides/hrsa/uds-plus/StructureDefinition/uds-plus-observation

This is the set of resources that conform to either of the profiles De-Identified UDS Plus Observation (http://fhir.org/guides/hrsa/uds-plus/StructureDefinition/uds-plus-observation) and De-Identified UDS Plus Observation (http://fhir.org/guides/hrsa/uds-plus/StructureDefinition/uds-plus-observation). E.g. what you have to deal with if you get resources conforming to one of them
