Y1 - 1993/// N2 - In the 1970s, we conceived of a rule explanation as supplying the causal and social context that justifies a rule, an objective documentation for why a rule is correct. Today we would call such descriptions post-hoc design rationales, not proving the rules’ correctness, but providing a means for later interpreting why the rule was written and facilitating later improvements.
