Mapping IDOC to message body

Hi,

Is it possible to map an entire  structure into a message body ?

We would normally map to a structure but in this case it will just a message body so we have an structure to go into an unstructured message body.

For example we have a structured file

MAterial Def

     Release

     Version

     Application

          Sender

          Reciever

etc....

the target is simply

Addmessage

     LocationID

     Messagebody

     MessageLabel

Is there a way to easily put everything in the structured message inside the message body ?

Thanks
