I think that his aphorism is simply a recognition that NO standard
can cover all cases that might arise when dealing with complex
matters, no matter how much thought went into it.  People are
fallible, and the standards they write are inevitably flawed in
some way, so a realistic implementor has to allow some slack or be
continually engaged in finger-pointing when something doesn't work.
