<para>Chg-rait does not require that all of the child changers have the same slot names: compound slot names are created by combining the slot names supplied by the child changers using the same shell-like syntax. For example, if the child changers return slots "<computeroutput>top</computeroutput>", "<computeroutput>strange</computeroutput>", and "<computeroutput>3</computeroutput>", then the RAIT changer will return "<computeroutput>{top,strange,3}</computeroutput>". This makes it possible to, for example, mirror data on tapes in slots 1-10 to tapes in slots 11-20 of the same robot, using two <command>chg-zd-mtx</command> child changers (and, naturally, two tape drives). In this arrangement, the first slot would be named <computeroutput>{1,11}</computeroutput>.</para>
