We would need a (data)type to cover value space of both xsd:string and 
rdf:LangTaggedString so you can write:

   skos:prefLabel rdfs:range rdf:String .

http://www.w3.org/TR/skos-reference/#S12

(If a datatype, empty value space - I don't think we can use 
rdf:PlainLiteral's lexical space without making it some sort of special 
case)
