 I think addr:country can be identified by existing borders, but I don't 
 know how much effort this would cause. If you look at only one node than 
 you will have to find the country borders for that node. But where are 
 they? Yes there is a (are there more) service in that will give you 
 this, but that requires more effort than downloading one node.

 As for addr:city, you can not get this from administrative regions in 
 the Netherlands. There is no complete admin_level=10 boundary in place. 
 And I'm certain it also is not complete in my neighouring countries 
 Germany and Belgium, if these boundaries exist there at all. I haven't 
 found them (but I only glanced at some areas).

 Regards,
 Maarten
