Thanks a lot, Michael! I had forgotten about this method, which is one 
of the finest approaches when having to build up nested groups. In the 
last days, I have been successful in applying this technique.

Thank you, David. I somehow had a wrong idea about the way keys are 
working. (And I'm sorry for having forged an incorrect test expression.) 
Using group-specific moded templates like Michael suggested is a much 
more elegant way of despatching than the case distinctions I thought of 
first.
