/**
* Adds the payload content to the SOAP message. How the content is added to the message depends
* on the <i>containment</i> of the payload ({@link IPayload#getContainment()}).
*
* <p>The default containment is {@link IPayload.Containment#ATTACHMENT} in which case the payload
* content as added as a SOAP attachment. The payload will be referred to from the ebMS header by
* the MIME Content-id of the MIME part. This Content-id MUST specified in the message meta-data
* ({@link IPayload#getPayloadURI()}).
*
* <p>When the containment is specified as {@link IPayload.Containment#EXTERNAL} no content will
* be added to SOAP message. It is assumed that transfer of the content takes place out of band.
*
* <p>When {@link IPayload.Containment#BODY} is specified as containment the content should be
* added to the SOAP Body. This requires the payload content to be a XML document. If the
* specified content is not, an exception is thrown.<br>
* <b>NOTE:</b> A payload included in the body is referred to from the ebMS header by the <code>id
* </code> attribute of the root element of the XML Document. The submitted message meta data
* however can also included a reference ({@see IPayload#getPayloadURI()}). In case both the
* payload and the message meta data included an id the submitter MUST ensure that the value is
* the same. If not the payload will not be included in the message and this method will throw an
* exception.
*
* @param p The payload that should be added to the message
* @param mc The Axis2 message context for the outgoing message
* @throws Exception When a problem occurs while adding the payload contents to the message
