A few internet references report that etags for the same underlying
resource but with different representation (xml, json ...) should have
different etags.
That is currently not the case. Added code to allow incorporation of
representation info into the etag. By default the representation is
"json", but future patches can pass the representation down and modify
flow to match requested representation.
