  /**
   * 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
