Hi Alistair, Daniel

Thanks for reading and commenting!

I agree that keeping the "domainless-ness" of SKOS 
labelling/documentation properties help solving a lot of problem (that's 
solution 4 in the wiki page).
One thing I would like to mention is that even with this option we 
should put something related on the subject of labelling/documentation 
of OWL classes in the current documentation.

Actually it was in the draft I prepared, but the "wikification" caused 
the disappearing of the note :-(
 http://lists.w3.org/Archives/Public/public-swd-wg/2007Jun/0018.html 
makes the point that applying labelling properties to a resource does 
not make it an instance of skos:Concept. However, there could be 
confusion: all existing SKOS documentation (e.g . 
http://www.w3.org/2004/02/skos/core#prefLabel) refers to these 
properties as applied to instances of skos:Concept.

Cheers,

Antoine
