  //   utilizing the ServantActivator and ServantLocator interfaces of
  //   the Servant Manager are implemented by this class.  These
  //   include initialisation procedures of the ServantActivator and
  //   ServantLocator, and creation of POAs with emphasis on the
  //   servant retention policy.

  // on the servant_retention_policy which decides the use of the
  // ServantActivator or ServantLocator interfaces. The

  // for the NONRETAIN policy.
