Validator rules are a good thing, but I think that "length of a way that has layer=*" to detect misuse of the layer tag is beside the point. Whatever threshold you use, there'll false-positives and false-negatives. How about something along the lines of "negative layer but no tunnel tag (or positive/bridge) and no/too many crossing ways" ? _______________________________________________ talk mailing list [email protected] https://lists.openstreetmap.org/listinfo/talk
