I'm not sure whether it matters, but with all due respect, this is not 
even partially a last call comment.  The window for submitting last call 
comments to RDFCore closed some time ago.  This is thus a post last call 

RDFCore is reviewing post last call comments and considering how to 
respond to them, so you can be assured that this comment will go through 
that process.
