Sure. That wasn't what I was referring to, though; my "rule" above was about 
when to choose single invocation and when to choose multiple invocations,
since you seemed to find the DES spec a little insufficient on that matter.
By defining the rule precisely we ensure all implementations make the same 
choice in all cases.
