1: Only very few objects have this tag. So I cannot require it.
2: In the same state there can be 2 villages with the same name.
3: I'm trying to match that I have the correct area. That it covers about
   the same geographic region is a sensible test to do.

So, please no discussion about is_in here. This has nothing to do with
the sanity-check.

Any constructive comments about different sanity-checks and matching-rules
I could add/change to find more of the areas automatically?
Currently from the test-runs I estimate that in about 1/10th of the cases
it can find a match.
