Yes, that can happen. No, they shouldn't be combined.

If it helps any, this is the index for a book. The larger stylesheet of 
which this solution will eventually be a part is for software user guides. 
Ideally, it should support anything you might see in the average index.

I have a working solution for three levels of index entries, because 
that's all I ever use. However, the problem of arbitrarily deep nested 
grouping interests me in its own right.

Thanks for the help.
