A similar  approach to the 206 response code (207 Partial Triples) could
be chosen so that caches not supporting vocabulary-negotiation must not
cache the response.

Another issue for caches is multiple serialization, if the response is a
graph a cache could cache the triples and deliver any serialization the
client requests. However the cache should be told if what matters is the
graph or if the resource represented is in fact an rdf/xml document
where serialization idiosyncrasies, comments, etc. do matter .
