RE: [SKOS] ISSUE-32 ConceptSchemeLabellingInteractions

My basic point is that I strongly agree that no 
two concepts in the same KOS be given the same
preferred lexical label in any given language, 
and I wish SKOS semantics would enforce this. If 
SKOS doesn't enforce this, then this will 
diminish interoperability across KOSs (there's no 
consistency in how people uniquely identify 
concepts), diminishing the value of SKOS.
