I don't see how we'd be adding any more confusion by adding a fourth type. Right now if someone tags something as railway=platform they have to figure out whether it is "always area" (*) or "way unless area=yes is present", and this is not at all obvious. Even more confusing are the barrier=* tags. I think they are of the type "always way", but I'm not 100% sure about that. The wiki lists barrier=city_wall as being a way or an area. But I think by area they just mean closed way. Is barrier=city_wall "always area" (*), "always way" or "way unless area=yes is present"? How is someone supposed to figure this out? Allowing area=no provides a simple method of dealing with cases where you are unsure: just tag area=yes/no explicitly. (*) I note, here, that "always area" doesn't mean "the way always represents an area", it means "the way always represents an area when it is closed". _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
