We had to choose which took effect, the referring <group ref="..."
.../>'s min- and maxOccurs, or the referred to's actual group (the
all/choice/sequence child of <group>).  We decided to go with the
referring one -- this seems to be what's wanted nine times out of ten, 
although _not_ always -- suggestions for improvements for the next
version welcome.
