I think the current definition is appropriate. Of course, a lot of thought was put into making sure that it wasn't so broad that it would capture organizations that were doing other activities, yet not so narrow that it would exclude organizations that were effectively doing the same thing. The words that were chosen were carefully thought through. We wanted to make sure that it wasn't too narrow or too broad and that it wouldn't miss something or go too far in either case.
