Composite Message Type

The set of static model definitions (wrappers and message types) that define the structures of the data that is transmitted by the Interaction. Committees will explicitly identify all message types (transmission wrapper, control act wrapper and payload) associated with a particular interaction.

In terms of structure an Interaction can be either a Message-based Interaction or a Batch-based Interaction. Interactions consist of:

1. a Batch Wrapper (conditional upon it being a Batch)
2. a Transmission Wrapper
3. a Trigger Event Control Act Wrapper (conditional)
4. Domain Content (optional)
