I'm very happy with the notion that partially specified reified statements are
allowed. If the decision had gone the other way presumably you could have used
the interpretation of bNodes as existentially quantified variables to model
this, viz:
    <site> <collects> _:1 .
    _:1    <rdf:type> <rdf:Statement> .
    _:1     <rdf:predicate> <p3p:birthdate> .
    _:1     <rdf:subject> _:2 .
    _:1     <rdf:object> _:3 .
