Thanks for catching this, Mike.     As you suggest, RIF-in-RDF is a RIF 
Working Group Note (not a Rec-Track document), so it's not appropriate 
to require implementing it for implementing the SPARQL RIF Core 
Entailment Regime.

I think the text in the spec could probably be clearer.  It says: "the 
URI for a RIF rule set (which may be encoded in RIF-XML or RIF-in-RDF)", 
without clarifying that implementation do not have to handle both.

So, I think we'll need to make that test case optional.

At ISWC I talked to you about the possibility of putting together a few 
more tests.   Any chance you've had the chance to do that?
