I'm commonly creating associatedStreet relations with multiple role=street members since there's no other way to easily map reality. I don't think it should be a problem. Most likely the people who first defined the relation didn't consider the possibility of split streets. I certainly don't consider it a 'bug' in the postcode finder. As for statistics on this, it should be quite easy for me to make a measurement this evening. -- Matt Williams http://milliams.com _______________________________________________ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb
