It was certainly my understanding that a formal standard like an ISO standard
must contain enough information that you could give it to a Martian who had
never even heard of, say, UNIX, let alone used it, but was otherwise well
versed in computer technology, and he/she/it should be able to write a
conforming implementation.  Stronger yet, if something is not mentioned
in the standard, even if it perhaps should have been, implementers should
be free to include it or not include it at their own discretion.
