I think it makes sense to put these definitions into the R2RML draft  
as well, because not every reader will be motivated to look them up in  
the SQL spec.

But I'm afraid this will have to wait until after FPWD.

If someone wants to start compiling relevant definitions from the SQL  
spec on the wiki, then the editors could use that as a basis for a new  
section in the draft.

Best,
Richard
