//
// = DESCRIPTION
//    Defines a factory that returns a specialized visitor object based on the
//    code generation state. This factory creates visitors associated with
//    Asynchronous Messaging Invocations (AMI) since, because of implied IDL,
//    state is not locally known at visitor creation time.
