|Used on these elements|
|Tools for this tag|
Tag used in cases where POI such as shop or museum and building were mapped as one object despite being two different objects, even with different names (violating One feature, one OSM element). In such cases this objects should be rather mapped as two separate objects.
addr:housename=* can and should be used if building name is part of the address
