SAOP MTOM/XOP Implementation

I have Wm7.1.2 and wants to handle large soap messages via MIME Attachment feature available in SOAP1.2.

I did create web service provider and changed the value of enable attachment to true in the properties.

Is that all I have to do or I have to pass and receive documents in special encoding or special way?

Your help will be much appreciated.

Regards.
