If it's agreed that no triple should be generated for this test case, 
then the SPARQL test is inadequate for finding implementation bugs. In 
particular, librdfa generates the triple:


which looks like a clear error, yet the test case does not detect it 
since it's only testing for absence of one specific triple. Some other 
implementations have different errors (treating it like a blank node).

I would suggest changing the query to say:

   # This is a negative test, no triples may be generated.
     ?s ?p ?o .
