Property valueSetVersion : WideString; (Read/Write)
The version of the valueSet in which no code was found.
valueSetVersion SHALL be provided when a valueSet is provided, and otherwise SHALL be null. The value of the valueSetVersion must properly identify a particular version of the value set following the rules defined by the value set or its publisher.
It is generally recommended that value set publishers specify that the version is identified by the date/time that the value set version is published, and that the publication process makes the date/time explicitly clearclear.
