How common is it for people to do this? I've seen the idea mentioned in various discussions on the wiki (and I think it's the cleanest approach), but it usually gets people arguing against it on the grounds that it makes the boundary less visible and more vulnerable if, for example, someone makes changes to the road without realizing it's part of the relation. -- ...computer contrarian of the first order... / http://aperiodic.net/phil/ PGP: 026A27F2 print: D200 5BDB FC4B B24A 9248 9F7A 4322 2D22 026A 27F2 --- -- And remember, this fix is only temporary, unless it works. -- Red Green ---- --- -- _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
