1) The "whole numbers" referred to the lanes tag. Width of course can
have fractional digits.
2) The width=4 should be a recommendation if the width - for whatever
reason - is not measured exactly. The recommend width should have two
properties: a) easy to remember, and b) for any data consumer it
should be clear, that this is "narrow". Because of a) I would take 4
and not 4.3 and because of b) we can not take 5.
