http://hl7.org/fhir/StructureDefinition/valueset-expand-group
Status: draft. Extension maintained by: HL7
This extension declares a group of concepts that is generated into the ValueSet.expansion.contains hierarchy when the expansion is generated for a UI. THere is no inherent assigned meaning to the hierarchy; it is used to help the user navigate the concepts. Each group has a display and/or a code, and a list of members, which are either concepts in the value set, or other groups (by code).
Comment:
Note that there are inter-relationships between concept status/properties and the way the groups are built; these are described and documented in the (value set hierarchical example)[d.html]. Note that this extension should be ignored when the expansion is not generated for UI.
Context of Use: Use on Element ID ValueSet.compose.include
