he actually raised two issues - one which you answered (on datatypes) 
and one which you didn't (on rdf:resource and on bnodes) -- this was 
for the latter - it's in 
http://lists.w3.org/Archives/Public/public-webont-comments/2003Jul/0014.html
and since it includes bnodes, I though Jeremy would be a good person to answer

yes - if you could get him to agree to move that one to rdf-logic it 
would be good.
