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
