I find the RDF mapping document to still be fairly confusing.  As  
well as the technical issues that Jeremy is raising, and the many  
typos (which can be fixed with a good edit) my primary objection is  
that by the end of the document I still cannot find a table of what  
terms are actually in the language and what aren't.  I also find a  
lot of terms added as syntactic sugar that are not made clear as to  
whether they are necessary or just provided for convenience - for  
example is
   x owl11:subObjectPropertyOf y
the same as
   x a owl:Object Property.
   x rdfs:subPropertyOf y.

I think issues like this are far more important to the OWL community  
I am representing (who are using bits and pieces of OWL as needed in  
their RDF apps, and want to be consistent with the spec while  
minimizing the number of terms they support) than are the deeper  
semantic issues.
  To put it another way - the intro to these documents mentions  
qualified cardinality restrictions as one of the key new  
functionalities added to OWL 1.1 -- can someone point me to the point  
in this document which mentions how to write such a thing in RDF?
   I realize that this is not meant to be a reference document, but  
without some sort of reference document, or significantly better  
examples of what the RDF produced for the important new OWL  
properties looks like, I see this document adding confusion for  
little current purpose.
