There's a clause in one of the map objects to show a layer only if 
another layer is present. Unfortunately, this is one of those cases that 
maddens documenters -- How to document something when a reader knows 
what they're looking for, but doesn't know what it's called.

Ah, using the "seek an ye shall find" method on the docs and I think 
what you want to look at is the LABELREQUIRES entry under LAYER in the 
MapServer Mapfile docs at http://mapserver.org/mapfile/layer.html.
