Why is there any debate about this at all? Why can't a type simply be added to the *specification* as an administrative detail and be done? Why isn't it trivial to add logical types? No change needs to be made to any existing software (or at least adding logical types shouldn't necessitate changes). -- Andrew Bell [email protected]
