We don't need a processing model. We just say, if you parse the input
document(s), then the result should be isomorphic to the rdf graph
described by the ntriples result document.

The preamble to the test case descriptions _does_ say that all test
case results should be interpreted by a person (ie, that we're not into
exhaustive conformance testing).

Dave's comment was the only input I received at the time from anyone who
is actually writing a parser that's in production use; so I complied
with his request.

Might I suggest we wait for Jeremy's document describing exactly what we
mean by "an RDF graph" and point to that for appropriate definitions of
equality/isomorphism/equivalence? It will (I hope) make this clear,
accurate, and moot.
