Nexus EMR profile for MessageHeader -- the routing envelope on an eReferral message bundle, consumed by the gateway's operation-routing middleware. Infrastructure rather than clinical content: no effective date, and R4 gives it no identifier element. First pass: the event vocabulary is not settled.
