17696	"misleading warning about ""duplicate housenumbers"""	dieterdreist	dieterdreist	"The duplicate housenumbers warning is forcing a certain mapping style on the mappers which is not universally useful: in Italy (and likely in some other place as well) the housenumbers refer to entrances (of properties or houses), so it is agreed they should be mapped as nodes.
On the other hand, mappers also want to store explicit address information of features. The result is duplicate occurences of addr:housenumber, one as address on a feature and one on the gate or entrance.
If we would require addr:housenumber to be unique we would have to create relations to assign the same address to multiple features for most of the features in the country."	defect	closed	normal		Core validator		needinfo	validator addr:housenumber duplicate
