But you do want them to be able to enter Paris, France as well as Paris,
Texas, USA. :-P  And in Germany, the state (Land) is not part of the
address, AFAIK, so Bavaria, or Freistaat Bayern, will never appear. And
it's most definitely not right to have to write Singapore, Singapore,
Singapore as an address. So I think some more flexibility is required,
as others have suggested.
