There wasn't anything specific I had in mind; I thought about it while messing around in my script-testing campaign. But, for the sake of argument, let's say using it as a means to post the current percentage of the attribute (health, for example). There are also a select few times in some d20 systems where you use the actual value of the attribute, rather than the modifier. (Our group has been using current value for attribute modifiers and max value for their actual value, so STR:4/18 for a character with 18 strength.) I suppose a workaround could be to have a separate attribute as the "max," but then you run into problems with linking attributes to a token's bars, so that isn't 100%.
