I've not explained well. My point is that different countries have postcodes that work at different scales. Some countries have multiple sets of postcodes for different levels of detail. When trying to process data on a world wide basis it would make life easier for data processors if boundary=post_code did not to refer to a completely different level of detail depending on the country. Effectively at the moment the postal_code tag can mean something very different in two different countries despite being the same tag. -- Brian _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
