As I mentioned on the tcon today, I think that lexical labels should 
be represented as classes, precisely because they need to be able to 
participate in relations with other classes. I do not see doing this 
an undesirable complication of SKOS--this is an issue of what 
representation is needed in order to express the  necessary relations.

To me, this approach adds undesirable complexity to SKOS.
