SWe need a more flexible solution.
For normal simple cases (small building, one address, placed on the map
close and unambigously near the Street of the address), put the number on
the building or on a node on the building polygon.
For more complex cases (anything from the size of an airport down the a
small single-address building closer to a street that's not in it's
address) use an address relation that ties together the different types of
addresses (nodes on the map) mentioned in Jareks post).
