Tim,
Not sure if this is what you are looking for, but the M&S does allow for
a reification without asserting the statement being reified.
e.g.,
<rdf:Statement id="foo">
<rdf:subject resource="KingOfFrance"/>
<rdf:predicate resource="livesIn"/>
<rdf:object resource="Paris"/>
</rdf:Statement>
This gives us the reification of (livesIn KingOfFrance Paris) without actually
asserting it.
