I think this may indicate a constraint of the life-time of the related 
objects. In the non-aggregate association, objects on either end may 
disappear (deleted in C++ parlance) at any time, but with the hollow 
diamond, you indicate that if this happens, we've got a problem. How you 
implement that is another story, and the raison d'etre of all the memory 
leak checkers and debugger I guess :-)
