Certainly - come closer to the fire, my son...

Actually, I can't think of a particularly good application for IDREFS, but I have used
ENTITIES quite often to emulate allowing multiple tokens from a token list. NAMES is too loose
and I may need more than one value, so a token list is out. By declaring entities and
assigning a notation that reflects their meaning, I get the best of both worlds.
