Are there cases where content negotiation would give a different RDF graph from the same resource? (Genuine question, not rhetoric.)


e.g. put a foo.rdf and a foo.ttl in a directory on an appropriately 
configured apache web server
ensure the two files contain non-isomorphic graphs, one in RDF/XML and 
one in Turtle

retrieve using two different user agents (browser etc) one configured to 
prefer RDF/XML the other to prefer Turtle
