Status: draft. Extension maintained by: Health Level Seven, Inc. - Structured Documents WG
Version specific identifier for the composition, assigned when each version is created/updated.
Comment:
While each resource, including the composition itself, has its own version identifier, this is a formal identifier for the logical version of the composition as a whole. It would remain constant if the resources were moved to a new server, and all got new individual resource versions, for example.
Context of Use: Use on Element ID Composition
