scope:

This part of ISO 20022 specifies the characteristics of the MessageTransportSystem required for an ISO 20022 BusinessTransaction and MessageDefinition. Changes to the value of the MessageTransport Characteristics can affect the BusinessTransaction and MessageDefinition. Each BusinessTransaction in the ISO 20022 Repository is associated with a MessageTransportMode. The MessageTransportMode specifies the values for the MessageTransportCharacteristics. This part of ISO 20022 specifically does not define the wire-level interoperability of message transports. The overall structure is of a layered specification so that ISO 20022 can be implemented over many message transports. This part of ISO 20022 defines only those characteristics required for interoperability at the business process and message level.
