You mean e.g at http://rdf.insee.fr/geo/DEP_05
you would get a placeholder containing no formal description beyond 
things like
rdfs:seeAlso http://rdf.insee.fr/geo/regions-2003.rdf#DEP_05
rdfs:seeAlso http://rdf.insee.fr/geo/departements-2003.rdf#DEP_05

I buy it.

Hmm. Not sure I would like that solution.
