So let me ask this question: If I have:

What is the base URI for that rdf:ID="Mustang"?
If it is http://www.example.org/library#
then

<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
          xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#"
          xmlns:owl="http://www.w3.org/2002/07/owl#"
          xml:base="http://www.example.org/library#">

    <owl:Thing rdf:ID="Mustang"/> 
    <owl:Thing rdf:about="#Mustang">
        <rdf:type rdf:resource="http://www.example.org/library#Mustang"/> 
    </owl:Thing>

</rdf:RDF>


is saying that

:Mustang rdf:type :Mustang.

or saying that :Mustang is in it's own extension
(and :myMustang is also in that extension)
That is indeed *possible* in RDF and OWL Full
