What is more important to me, and this is question for all who know,
how to cope boundaries *between* two areas, like administrative
ones? How to cope with boundaries of different administrative
levels? If a line is a boundary between communes it is also a
boundry of respective provinces.

Not necessarily - it could be at the moment, or it could not be. There
are examples (in the UK at least) of overlaps.

Do you mean that a commune (the lowest level of self government) can be part of more than one unit of each of higher levels? Like this?

I am talking here about administrative boundaries not some sort of customary ones.

I haven't written that earlier but what should I do if the boundary goes along some other way like railroad, river or highway? Should I draw another way right besides the road or tag one way as both the road and the boundary?

If the former then I think sooner or later we should develop separate layers for different features of the map. Editing could be much easier then.
