Maybe its not so bad as I first thought.  If we decide that the answer to 
test case A is yes and the answer to test case C is no, then we will need 
some magic in the model theory to handle rdf:object (per my recent 
post).  I guess it would mean applying the same magic to the ordinal 
properties.

Hmm, the question is which.  The later seems to imply, if one puts a 
literal in a container, then one doesn't know what it denotes.
