Antoine, I would be happiest if the domain of foaf:focus remained skos:Concept. The axioms in SKOS-XL are good enough that I'm willing to believe a set of skos:Concepts in a skos:ConceptScheme constitutes a "value vocabulary" regardless of whether SKOS-XL is being used explicitly. I'm less comfortable believing skos:Concepts that *aren't* bound to a skos:ConceptScheme qualify for "value vocabulary" status. I agree with your assessment of either end of foaf:focus being reasonable objects of dc:subject. It would be nice if there was an axiom specified somewhere to formalize this.
