	Well, in principle they're stackable, but we
	don't have a mechanism for stacking them!
	Tim and I were the discussants, when trying
	to figure out how to document them.

 	And that sounds good... the equivalents are something like:
	requisite	you must pass through this layer
	required	?
	optional	you need not go here
	sufficient	you don't need any more layers

	In a stacking architecture, this sounds  more than
	 sufficient...
