Hi,
If my interpretation is correct, it says that all those types of highway are considered as unpaved, unless there is a surface, tracktype, smoothness AND sac_scale parameter!
Rule is OK. If you negate conjunction (by use of "unless"), then you should use disjunction of negations: highway is unpaved when there is *no* surface and *no* tracktype and ... equivalent: highway is unpaved unless there is surface or tracktype or ... -- Best regards, Andrzej
