If RDF is the "odd one out" then it does seem ... unfortunate. The
application/rdf+xml type has a good amount of deployment though, and
it seems unfair to change the rules for those publishers by altering
the meaning of their existing markup, links and data. Would a
compromise design be to include a special case exception for
application/rdf+xml in the generic processing rules? Hardly elegant,
I'll grant you, but perhaps a reasonable compromise?
