OK, so this is the bit I didn't understand :) I thought they would be  
configured as per OWL-x/RDFS inferences, i.e. it's some external  
mechanism that SPARQL has no direct control over. Perhaps that's not  
how RIF is used in practice though?

I have to admit I'm not as familiar with RIF as I'd like.
