Dear Jeremy,

Thank you for your comment
on the OWL 2 Web Ontology Language last call drafts.

Thank you for pointing out this problem. The Syntactic Conformance  
section of the Conformance and Test Cases document (see [1]) has been  
revised to be clearer in general and to rectify these problems in  
particular. The main definitions of the different kinds of ontology  
documents now refer explicitly to the RDF/XML syntax and are now  
complete definitions, e.g.:

"An OWL 2 DL ontology document is an OWL 2 Full ontology document  
that can be successfully parsed using the canonical parsing process  
as defined in the OWL 2 Syntax specification [OWL 2 Specification]  
and the procedure for mapping from RDF graphs to the structural  
specification described in the OWL 2 Mapping to RDF Graphs [OWL 2  
Mapping to RDF Graphs] to produce an instance of the OWL 2 ontology  
class satisfying all of the restrictions described in Section 3 of  
the OWL 2 Syntax specification [OWL 2 Specification]."

Similarly, the example is now specific to the XML syntax. It says "An  
XML document is an OWL 2 DL ontology document iff [certain conditions  
are met]"; i.e., an XML document is an OWL 2 DL ontology document if  
said conditions are met, and it is not an OWL 2 DL ontology document  
if said conditions are not met.
