That's a six-criteria statement, which isn't all that hard to represent in some form of classification system. But that's categorization for scientific purposes. As has been recognized here, there are also cultural purposes for such categorizations. And those criteria are far different. That's a point I've been trying to make for quite some time. -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain
