No, and it can't be, because that would not be legal RDF.
DAML+OIL ontologies look like
<rdf:RDF ...>
<daml:Ontology>
<daml:imports ...>
</daml:Ontology>
<daml:Class foo>
....
</daml:Class>
...
</rdf:RDF>
This cannot be transformed into
<rdf:RDF ...>
<daml:Ontology>
<daml:imports ...>
<daml:Class foo>
....
</daml:Class>
...
</daml:Ontology>
</rdf:RDF>
because it would break the ``striping'' of RDF.
However, in some sense, a DAML+OIL ontology *has* a tag that wraps all the
statements that are "in" the ontology (and the ontology header elements).
The tag is the rdf:RDF tag that encloses all RDF documents.
