I was worried that was a lot more mechanism, and that given where we  
were in the process, the desire to get something in to this release  
of OWL, and the desire to keep to schedule and move quickly towards  
last call, the amount of work associated with doing that might have  
been considered too much. I didn't want to have proposing that much  
change put the possibility of getting *something* in this space out  
of reach.

In addition there were two technical details which I wasn't sure were  
covered by the paper. The first is annotations on annotations. I did  
want to make sure some version of this is possible as I am aware of  
several use cases in current projects that need it. The second was  
the issue of how to view that proposal from an RDF point of view.

I did note that the reification of the axioms and associated ontology  
of OWL axioms proposed by the paper seems to not be incompatible with  
what I've proposed- in the sense that I can see how one could script  
the creation of the reified axioms, and then import that into the  
second file.

However, I like that paper and its approach and if the WG were wiling  
to seriously consider what it proposes I'd certainly support that.
