It is crucial because it bears on the conditions under which it makes practical and logical sense to assert the identity of two individuals of type skos:Label. This is the fundamental question that all proposals following the "terms-as-classes" pattern must address.

Good point, should have made this clear. As skos:Label is just a support class for the literal, my initial reaction was that a liretal can only have one skos:Label attached to it  But this will not work in practice, as literals may be used as terms in several vocabularies. The only constraint that makes sense, I think, is to require that literals only have one lLabel within one particular ConceptScheme. Would this work?
