However a rendering engine that's iterating through objects could take: amenity=toilets;drinking_water fee=no opening_hours=24/7 toilets:position=seated;urinal And expand it to: amenity=toilets fee=no opening_hours=24/7 toilets:position=seated;urinal amenity=drinking_water fee=no opening_hours=24/7 toilets:position=seated;urinal But quickly you have tag pollution and it is not clear semantically which tag is the "main tag", and which tags refer to which amenity. Somewhat clearer is: amenity=toilets drinking_water=yes fee=no opening_hours=24/7 toilets:position=seated;urinal Which would expand to: amenity=toilets fee=no opening_hours=24/7 toilets:position=seated;urinal amenity=drinking_water
