my2c i would seriously advice against using triples with http://schema.rdfs.org . That would be totally and entirely validating their claim that either you impose things or fragmentation will distroy everything and that talking to the community is a waste of time. For how little this matters really - i'd really advice anyone wanting to produce RDFa of schema to live with it and use direct http://schema.org uris as per their example in RDFa.
