There are various ways to regard this occurence.

If that is the case then one has a rule containing a list of restrictions, and a corresponding list of the types of rules to which they apply. If you regard this latter list as part of the restriction then I think one is inexorably drawn to the first interpretation above. So I would say that a phrase like "All future rules must include the word udder" contains a restriction ("include the word udder") and a separate description of the rules to which is applies ("All future rules"). In the light of the above, I hope it becomes clear that I do not agree that > 178:2 then only requires rules not to restrict themselves, rather > than to requiring them to disobey any restrictions they are placing > on other rules. My imaginary rule includes the word "udder", and thus obeys the restriction "include the word udder", so would be INVALID. If my rule has said "All future rules must not include the word udder" then it would not obey the restriction "do not include the word udder" and so would be VALID (all other things being equal). > I hope that's clear!
