00042      * (QoP) for invocation on a per-object basis.  For example, it
00043      * can be set as a policy override using the standard

00045      * @par
00046      * This policy can be created by using the
00047      * CORBA::ORB::create_policy() method by passing it the
00048      * Security::SecQOPPolicy policy type, and the appropriate
00049      * Security::QOP enumeration (inserted into a CORBA::Any).
