Composition

Code system

Code	Display	Definition
consequence	Consequence	The message represents/requests a change that should not be processed more than once; e.g., making a booking for an appointment.
currency	Currency	The message represents a response to query for current information. Retrospective processing is wrong and/or wasteful.
notification	Notification	The content is not necessarily intended to be current, and it can be reprocessed, though there may be version issues created by processing old notifications.
