"Requires" constraint refers to causes, not effects
Currently, the text groups the "requires" constraint into the paragraph on constraints of effects. However, (as the text itself correctly states), "requires" is a constraint on causes. Hence, this needs rewriting. —Preceding unsigned comment added by 130.208.71.23 (talk) 12:30, 16 March 2011 (UTC)
