Hi Birte, all,

Do you think we should add a test case like that:

 G: 
   :s :p "foo"

 Q: 
 SELECT ?L 
 WHERE { ?L a rdfs:Literal }
 
Similarly:

 G: 
   :s :p 1

 Q: 
 SELECT ?L 
 WHERE { ?L a xsd:integer }


Obviously, those will not give an answer, but some people might expect those to return surrogate blank nodes... a colleague of mine just came to me with that (in a different context), and I thought I might share it.
