Good point. This is the trouble with trying to make a MECE (mutually exclusive, completely exhaustive) list. They are hard to make well. Apologies....
Unless others feel strongly otherwise, I would suggest putting the EX5 in all the categories it applies to, since you might use it in any of those roles.
