What is the need of Message Type

Hello every one,

I am new to XI but i have involved in XI project. I am having a question like we need DATA TYPE as it contain the whole structure we need MESSAGE INTERFACE as it will say whether the communication is SYN ,ASYN , INBOUND , OUTBOUND or ABSTRACT. But Why we need this MESSAGE TYPE, what is the use of this.Please don't show me the links. I hope there is a specific purpose for MESSAGE TYPE. Help me out to figure out that purpose

Message type is the wrapper of data type.

A message type comprises a data type that describes the structure of a message

In XI we are using XML langauge therefore we need a Root element in our message that root element is added by Messagr type means data type is just an abstarct structure and message type add root element to data type

and root element is used in mapping the structures.

hope you get some clue .
