In that case, you can iterate over and de-duplicate from both groups.

In fact, you can define two keys for the two groups with the same name, 
only different "use" values, which could help in this.

I'd be more explicit about this, except (a) it's much harder to write up 
without some sample code to chew on (please post again with your source and 
problem statement?), and (b) I'm in a time crunch today.

But I learned this trick from Jeni: I think if you look in the FAQ and on 
Jeni's site (http://www.jenitennison.com), where grouping is covered in 
some detail, you could find something.

Cheers,
Wendell
