 * The OSPPMsgDescGetName includes two different implementations: the
 * first is safer and the second has higher performance. The safer option
 * does an exhaustive search through the descriptors array. The second
 * simply uses the part ID as an index into that array. The risk with the
 * second approach is that it requires that the array be built correctly,
 * with elements in the precise, right order. If you enable the second
 * approach, it is essential to test the array ordering using the the code
 * in the included main() procedures in the individual components.
