Good point; the statement is not referring to the subsumption, but to
FOSIchildSafe.

<owl:Class rdf:ID="FOSIchildSafe">
  <rdfs:subClassOf wdr:ChildSafe/>
</owl:Class>

<rdf:Statement rdf:about="#FOSIchildSafe">
  <wdr:includeHost "example.org"^^xsd:string/>
</rdf:Statement>


Or s'thing like declaring an RDF meta-property that has owl:Class as
it's domain:

<rdf:Property rdf:ID="includesHost">
  <rdfs:domain owl:Class"/>
  <rdfs:range rdf:resource="http://www.w3.org/2001/XMLSchema#string"/>
</rdf:Property>

<owl:Class rdf:ID="FOSIchildSafe">
  <rdfs:subClassOf wdr:ChildSafe/>
  <wdr:includeHost>example.org^^xsd:string</includesHost>
</owl:Class>
