 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.

<rdf:Statement id="foo">
    <rdf:subject resource="KingOfFrance"/>
    <rdf:predicate resource="livesIn"/>
    <rdf:object  resource="Paris"/>

This gives us the reification of (livesIn KingOfFrance Paris) without actually
asserting it.
