Msg subtype
The subtypes of the Msg category represent EDIFACT messages.
The sub-types of Fversion (for example, F93_2) are all the messages in the EDIFACT version. The name of each message is the value of the MsgType Element in the UNH.
A message begins with a UNH and ends with a UNT.
The middle component is the type that represents the actual contents of the message. These types are found under the version-specific category, for example, the V93_2 category in the edif93_2 schemas.
Each message has a unique value for the MsgType Element. The value is specified by the component rule on the UNH component. For example, the component rule states that the MsgType Element of the UNH in the BAPLTE message is BAPLTE. Each message has a similar component rule.
