<tt><font size=2>My question is about stacks that are not nested. Suppose,
for example, that I create a stack that implements a shared service. Later
I create a separate stack that uses that shared service. When creating
that client stack, I would like to have a way of talking about its relationships
with the service stack.</font></tt>
