Are properties from a context-constrained class inherited by subclasses?

Hi Folks,

Suppose that I have this class heirarchy:

        River
           |
      Flueve
          |
       Blah

Suppose that the property, emptiesInto, has a domain of River:

     <owl:ObjectProperty rdf:ID="emptiesInto">
           <rdfs:domain rdf:resource="#River"/>
           <rdfs:range rdf:resource="#BodyOfWater"/>
     </owl:ObjectProperty>

Suppose the Flueve constrains emptiesInto to have a range of #Sea:

     <owl:Class rdf:ID="Flueve">
         <rdfs:subClassOf rdf:resource="#River"/>
          <rdfs:subClassOf>
                <owl:Restriction>
                        <owl:onProperty rdf:resource="#emptiesInto"/>
                        <owl:allValuesFrom rdf:resource="#Sea"/>
                </owl:Restriction>
          </rdfs:subClassOf>
     </owl:Class>

Question: what is the range of emptiesInto when used in the Blah
Class?   /Roger
