Taking a different route to the point Dan is making, how about this:
A uri can identify a document.
A uri can identify a document location. This is also a url, a subclass 
of a uri.
A uri can identify a document subject.
Anything can be a document subject.

Bearing in mind the above, you can have a document (xyz.owl) that 
describes an ontology. Thus, said document (xyz.owl) can have a uri 
distinct from the ontology uri (the subject of xyx.owl).

Here is some Virtuoso SPASQL that demonstrates my point:

### Nepomuk Personal Information Management Ontology cleanup
### Problem: the descriptor document (doc describing the ontology is 
missing critical relations such as: rdfs:isDefinedBy and 
wdrs:describedby ).
### Solution: add the missing relations to a named graph in Virtuoso via 
the SPASQL below.
### Important points: the ontology has its own uri distinct from the uri 
(basically url) of the descriptor document.


INSERT INTO <http://www.semanticdesktop.org/ontologies/2007/11/01/pimo/>
{?s rdfs:isDefinedBy 
<http://www.semanticdesktop.org/ontologies/2007/11/01/pimo#> .
<http://www.semanticdesktop.org/ontologies/2007/11/01/pimo#> 
<http://open.vocab.org/terms/defines> ?s.
<http://www.semanticdesktop.org/ontologies/2007/11/01/pimo#> a 
owl:Ontology .
?s <http://www.w3.org/2007/05/powder-s#describedby> 
<http://www.semanticdesktop.org/ontologies/2007/11/01/pimo/>}
FROM <http://www.semanticdesktop.org/ontologies/2007/11/01/pimo/>
WHERE { optional {?s rdfs:subClassOf ?o}. optional {?s 
rdfs:subPropertyOf ?o}. optional {?s owl:equivalentClass ?o}. optional 
{?s owl:equivalentProperty ?o}. optional {?s a ?o}}


Here's are urls of  documents that showcases the effects of the above:

1. 
http://uriburner.com/describe/?url=http%3A%2F%2Fwww.semanticdesktop.org%2Fontologies%2F2007%2F11%2F01%2Fpimo%23 
-- ontology as subject of a descriptor document

2. 
http://uriburner.com/describe/?url=http%3A%2F%2Fschemapedia.com%2Fschemas%2Fsemanticdesktop-pimo 
-- descriptor document that has an ontology as its primary topic (or 
subject).


I hope this helps.
