[Tagging] capital and state_capital: how are they being used in your country?

Hi Trebien,

I investigated a little about the capital=8 tag (which is 84.67% of it's 9
989 values), and it seems it's being used differently than what we thought
initially.
Most of these cases have something like admin_level=8 + capital=8.

I don't have the time right now to investigate it fully, but it seems it's
like Trebien guessed before: it's probably the result of a import:

   - http://www.openstreetmap.org/user/egrn
   - http://osm.mapki.com/history/node.php?id=34095951


You can use the following Overpass query to see the first 500 nodes with
the tag capital=8 + admin_level=8: http://overpass-turbo.eu/s/3n4
(remove limit="500" from the <print> statement to see all 8000+ nodes).
