Honest question: are there capitals for something besides countries and

If not, we could keep it simple:
* capital=yes for country capitals
* state_capital=yes for state capitals (already in use in some parts of
America <http://taginfo.openstreetmap.org/keys/state_capital#map>).

PS: Taginfo just released some new functionality, which allow us to compare
the different uses of the different keys "capital" around the world:

key capital=* seems to be incorrectly tagged).
I'm not saying we should use the others, just though it was interesting.
