In the pattern, you mean? I guess not, though if we allow this then 
we might want to draw reader attention to the non-RDF-ish nature of 
those patterns, and that they amount to asking "does a predicate 
exist such that...". That is, any answer binding must instantiate the 
bnode to a URIref. Or, of course, we could just prohibit them :-)

BTW, I don't see that this is affected by the subgraph/entailment 
decision. Am I missing something?
