I had indeed understood this. But it was not very explicit from the 
examples alone, and I wanted to have confirmation of what would happen 
in the antonymy case.

Argh. So if I would try to clarify the information found at the top of 
[0] (yes, zero ;-) then your "minmal label relation" [4] competes with 
your previous "Label Annotation" [2] and Guus' "Label Relation" [1]. And 
then the best of the three should be compared to the "Simple extension" 
by Guus [4] which proposes a less systematic approach to the 
Term-as-class option

Notice that all the proposals relying on sort of reification of the 
label link face the important problem raised by Jon in [5]: asserting 
links between labels should somehow be contextualized, and I'm not sure 
you could do with so little semantics for your seeLabelRelation 
property. Indeed, since attaching a LabelRelation to a concept is not 
optimal as I've tried to show, I would propose to contextualize it by 
attaching it to the ConceptScheme instance itself...

Notice also that this contextualization issue may also occur for the 
term-as-class part of Guus' "Simple Extension" [3]. Perhaps a better way 
is just to ignore this problem for now, and to postpone it till we solve 
the related SemanticRelationshipContainment issue [6]. I really don't 
like how all these issues are related...

Cheers,

Antoine
