I think this issue on coordination with subdivision is slightly 
different. In my mind it would be better to sort it by solving the 
issues 40 [1] on coordination and 60 [2] on not-indexing concept 
entities (the motivation for my introducing this issue was partly to 
represent in SKOS conceptual entities that are not full-fledge concepts, 
cf. requirement R-IndexingAndNonIndexingConcepts [3])

Cheers,

Antoine
