I have a problem with {tcadu} - I don't understand the explanation
of its place structure. It might be due to fact, that my English
is not good enough.

x1 is a town/city of metropolitan area x2, in political unit x3,
serving hinterland/region x4

{la berlin. tcadu} - Berlin is a city. No problem so far, but what
are x2, x3 and x4 here? Could you give an example?
