Documentation: This is not an HL7 datatype. The intent of this class is to define a concept that subsumes a collection of concepts in a terminology. For example, "systolic blood pressure" in snomed CT contains s "target systolic blood pressure" subclass. To express the notion of measured systolic blood pressure, one can say "systolic blood pressure (SNOMED)" and (not "target systolic blood pressure")
