I'm not sure about this one: >5. A resource typed as a <soks:Concept> may have at most one value for ><soks:prefLabel> > different facets might have different preferred labels (the obvious problem). I am not sure if you can account for that in OWL, although I would have thought you can. But a single Concept might have a couple of preferred labels too. I am thinking of use cases that guess which Concept is being referred to, and being a preferred label is an obvious way to rank possible choices. Also, in merging two thesauri, is there really a need to choose a single preferred term, given that the RDF key to the meaning is the concept? The others all make sense to me.
