I don't see why clearing a single named stack would ever be needed.
Stuff goes on to stacks as rules fire "begin", and gets removed as rules
fire "end"; everything balances. Clearing a stack part-way through a
digestion is a rather odd concept.
Is there a particular scenario where this operation is needed?
Note that the method Digester.clear() will clear all sorts of stuff,
including all named stacks. This is never expected to be called *during*
a parse of course. Actually, it shouldn't *ever* be called, as described
in the javadoc, but it's there in case people want to live dangerously.
