No.
Conventionally the ontology element is the first child of the rdf element,
and the triples in the ontology are shown in other children of the rdf
element.
e.g.
<rdf:RDF>
<daml:Ontology rdf:about="">
<daml:version>1.0</daml:version>
<daml:Ontology>
<daml:Class rdf:ID="Foo" />
<!-- ... -->
</rdf:RDF>
The "" in the rdf:about refers to the current document. (it is referred to
in RFC2396 as a same document reference)
Peter's analysis about documents unfortunately makes a lot of sense, and
points to a weakness of RDF's triple model that there is no treatment of
documents.
