     * This policy can be used to affect the quality of protection
     * (QoP) for invocation on a per-object basis.  For example, it
     * can be set as a policy override using the standard
     * CORBA::Object::_set_policy_overrides() method.

     * CORBA::ORB::create_policy() method by passing it the
     * Security::SecQOPPolicy policy type, and the appropriate
     * Security::QOP enumeration (inserted into a CORBA::Any).
