Ah, no problem with non strictly nesting, overlapping areas.
We already have that on the French borderline with /Parc naturel 
régional Scarpe-Escaut/ ;-)
But please, please, please avoid sharing borderlines.
To each area its own borderline, overlapping if needed, just like no 
sharing roads and rivers.

Borderlines should nest in multilinestring (or route) but most sofware 
does not support that.
That is why we have e.g. communities and arrondissements fighting for 
the same borders and monopolizing their data.

This said, it would be much more simple in all respects if Belgium had 
only municipalities and provinces.  Quadrilingual, if no more. See CH.
With friendly international names like Waterloo/-//Water-L'eau/ ;-)

Totrevoirawsbye,

André.
