/**
 * This a test of the Signature Confirmation functionality that is contained in the

 * the signature. The responder processes the inbound SOAP message and saves the received
 * signature. Then in the responding message the received signature is attached in the
 * form of a wsse11:SignatureConfirmation blob. The requestor processes this blob and
 * checks to make sure that the signature value contained therein matches the saved value.
