[OSM-talk] Populated places: how to use is_in tag?

[David Earl]

On the other hand, the name finder searches already recognise is_in, so 
that searches like "Murano, Veneto" should work if is_in is used.

is_in has typically been used like this:
   is_in=commune,province,region,country
(that is, working outwards and separated by commas).
