Hi Seshu,

A message type comprises a data type that describes the structure of a message. For technical reasons, a data type alone is not sufficient to describe the instance of a message: Data types are defined in XML Schema as abstract types that are not yet tied to an element. You can only describe an instance of a message when you have specified a data type as an element type. Therefore, a message type defines the root element of a message.

Thanks,

Naga.
