Dear Marko,

Thank you for your comment
     <http://lists.w3.org/Archives/Public/public-owl-comments/2009Oct/0010.html>
on the OWL 2 Web Ontology Language last call drafts.

Thank you very much for the thorough comments. We have implemented all the proposed changes to make the OWL/XML serialization validate, see the according diffs [1] and [2]. As to the suggested alternative handling of the rdf: and xsd: namespaces, we encountered problems when applying conversion tools [3] to the modified version, whence we preferred to stick with the current (correct) way of specifying them.

I have found some typos in the OWL/XML version of the complete sample  
ontology given in the OWL 2 Primer in Appendix 13 at

<http://www.w3.org/2007/OWL/wiki/Primer#Appendix:_The_Complete_Sample_Ontology 
 >

that make the ontology fail to validate against the given XML schema.  
Applying the substitutions given at the end of this message makes the  
ontology valid.
Furthermore, the entity declarations at the head of the ontology

<!DOCTYPE Ontology [
<!ENTITY xsd "http://www.w3.org/2001/XMLSchema#" >
<!ENTITY rdfs "http://www.w3.org/2000/01/rdf-schema#" >
]>

could be removed if the references "&xsd;" and "&rdfs;" to these  
entities would be replaced by the corresponding default prefix names  
"xsd:" and "rdfs:".

I strongly suggest that all examples given in any syntax to respect  
the specification,
Marko Luther
