Testing that bit with our current assumed
inference rules we can't prove that

:a rdfs:_25 :b.


:a rdf:type rdfs:Container.

Can anyone tell me if we have decided this?

Should the domains of  rdf:_1, rdf:_2, etc., be rdfs:Container or
rdfs:Resource? Peter tells me that email discussions about rdf:li
say they should be the latter, ie. it is OK to apply these properties
to non-containers. Is that right?
