personally, i would prefer if this were implemented at the editor level - i.e. when i add a 'bridge = yes' tag, it also adds a 'layer=1' tag as well, so i can either accept, or occasionally change it. where possible, and appropriate, i would prefer things like this be in the open _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk
