Dear Jan,

Thank you for your comment
      <http://lists.w3.org/Archives/Public/public-owl-comments/ 
2009Jan/0050.html>
on the OWL 2 Web Ontology Language last call drafts.

You have noticed that, in the current specification of OWL 2, only  
*unary* datatype relatations (facets) are supported and that, in  
theory, this restriction is unnecessary. The syntax is defined,  
however, in such a way that it can be easily extended to datatype  
relatations (facets) of arity larger than one. It is possible that  
such an extension (to the syntax and the semantics) will be published  
later as a separate document; this will depend on the state of and  
experiences with implementations.

Please acknowledge receipt of this email to <mailto:public-owl- 
comments@w3.org> (replying to this email should suffice). In your  
acknowledgment please let us know whether or not you are satisfied  
with the working group's response to your comment.

Regards,
Uli Sattler
