[mkgmap-dev] Configurable region/city mapping in address search?

It occurred to me that the definition of a region should probably depend on the area of the map that is being built. For a map that comprises most of Europe, a meaningful region could be the country. A map of a single country or closely related countries, such as the BeNeLux or the Baltic countries might use state or province for the regions. A map of a federal republic such as Germany or the USA could use the state for the region. A map of a single state might use city as the region and suburb or village (German: Ortsteil) as the city. Is the mapping of regions and cities configurable? How? I guess that one would get most flexibility with a location bounds file. Marko
