I'm not sure I understand the problem.  Simplifying your
example for clarity:

  <rdf:RDF>
    <rdf:Statement>
      <rdf:subject    rdf:about="mary"/>
      <rdf:predicate  rdf:about="wants to marry"/>
      <rdf:object     rdf:about="Fred"/>
      <foo:believedBy rdf:about="John"/>
    </rdf:Statement>
  </rdf:RDF>

as I understand things, the above quotes 
(wants to marry, mary, Fred) without asserting it, if
I understand correctly what you mean by 'quotes'.

Please could you give a concrete example of the bug you
had in mind?
