> From the beginning I have struggled with chapter 3.1.3 of the OWL Guide.
So let me ask this question: If I have:

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

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
