The problem with "closed collections" is it's not obvious to me how they 
can be "closed", given the lack of semantics of the properties involved. 
   Presumably RDF/XML will generate the well-structured lists we imagine 
this is for, but it seems to me people can write all sorts of weird 
stuff using rdf:first, rdf:rest, and so on, and (e.g.) add those 
properties to things that started off as those well-structured lists. 
This is why I don't talk about the presumed "closed" aspects of these 
collections in the Primer.
