 * @class TAO_QOPPolicy
 *
 * @brief Implementation of the SecurityLevel2::QOPPolicy interface.
 *
 * 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.
 * @par
 * This policy can be created by using the CORBA::ORB::create_policy()
 * method by passing it the Security::SecQOPPolicy policy
 * type, and the appropriate Security::QOP enumeration (inserted into
 * a CORBA::Any).
