            Partial support for recursive structs and unions. Only available
            for the erl_corba backend and requires that Light IFR is used.
            I.e. the IC option {light_ifr, true} and that Orber is configured
            in such a way that Light IFR is activated. Recursive TypeCode is
            currently not supported.</p>
