David proposes some modifications.  Any objections?

I think that I have inadvertently distorted the definition.  Original words 
from Lynne said "A complete set of use cases captures all...".  I can work 
on rectifying that confusion.

Does anyone object to reworking it so that it has this sense?

I sympathize with this -- don't raise the bar too high.  There is some 
subjectivity in "sufficient", but there might also be some subjectivity in 
measuring "complete".
