Personally I think it'd be good to tag the road as primary *and* secondary, i.e. that we should have 'highway=primary;secondary'. This makes it possible to see how many km of secondary roads there are in an area, or to highlight only road 172. *However* most of the renderers can't deal with semi-colons well. Just see Dermot McNally's post in late May about "Potlatch and the evil semicolons". I don't really like mapping for the renderer though. :) Rory _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk
