well, as I tried and explained, I had a conclusion like

<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
         xmlns:owl="http://www.w3.org/2002/07/owl#">
  <rdf:Description rdf:about="http://www.example.org/foo#object">
    <rdf:type rdf:parseType="Collection">
      <rdf:Description>
        <rdf:type 
rdf:resource="http://www.w3.org/2002/07/owl#Restriction"/>
        <owl:maxCardinality>1</owl:maxCardinality>
        <owl:onProperty rdf:resource="http://www.example.org/foo#prop"/>
      </rdf:Description>
    </rdf:type>
  </rdf:Description>
</rdf:RDF>

but that is quite different than yours
and I'm indeed not convinced about having
existentials in inference rule conclusions
(except for closed lists denoting sequences)
