Do you mean that a commune (the lowest level of self government) can

yes. some examples:
i think turkey lies partly in europe, partly in asia?
There are other examples at even this high a level as well.
Parts of France are in South America (lots of people are surprised to
find that Brazil has a land border with the EU). Parts of Spain are in
Africa (Melilla, Ceuta, etc).
Please, are we talking about administrative boundaries? OK about
boundaries and is_in. That is the problem. I think, and I do it,
that, is in should reflect administrative structure. Not at all
levels but most. E.g.
place=country,name=Polska,name:en=Poland,is_in=Europe
but
place=town,name=Mszczonów,is_in=Mszczonów,żyrardowski,mazowieckie,Polska
Mszczonów is the name of the town as well as the name of the commune
(the first element of is_in). Next there are two levels of Polish
administration, and the name of the country.
For this French territory in South America it would be.
place=country,name=Guyane,is_in=South America
then
place=city,name=Cayaenne,is_in=Guyane,...
Guyane becomes something kind of country in terms of OSM logic.
Its connection with France is not essential in any way for drwaing a
map.
I've been thinking about connection between boundaries (ways) and
places (nodes) recently and the only method that occured to me OK
was *boudary_of* tag with a value of the id of the place node.
However I havn't thought about it in terms of relations, yet.
