I see how that's a problem. However, I'd say the best solution is to just pick some unique way to describe it, and then it can be retagged later when we can come up with a better scheme. Really, this is one of those situations that's going to require editor and/or API improvements to map correctly. But get the data in the db, and the situation can be better analyzed.

What if you can walk on the road, but not next to it? _______________________________________________ Tagging mailing list [email protected] http://lists.openstreetmap.org/listinfo/tagging
