Value Set Versioning
Value set versioning - The model in section 5.3 needs to include versioning for value sets, and a version parameter is needed in several functions (e.g. isCodeInValueSet). This is particularly true because there isn't a single release for all V3 messages - some will pass membership ballot, value sets will change, and then other specifications based on the value set will pass membership ballot. If committees have declared CNE value sets, these are fixed at the time the ballot passes.
