Postscript: yep, you're right - really don't know how I missed that before. Not that is says much, cross-checking through the standard, all that's really said is that the aeroplane has to behave acceptably up to that ceiling. So, just a bit of commonsense really - largely I think ignored as most part 23 aeroplanes don't declare a ceiling in my experience.
