Hmm, Sandro's and my idea was rather the other way around, cf.
 http://www.w3.org/2009/sparql/meeting/2010-12-01
i.e. copy the spec to our SPARQL document and then see whether the RIF-in-RDF [2] doc goes further than a Note (upon which we can't really rely):

The rationale is:
 - this way doesn't to put us under stress to put the RIF-in-RDF doc forward to Rec (in the light of our tight schedule and other things on our plate, that seems preferable)
 - if I understood Sandro correctly, when the Second Edition for XSD comes out, we will anyways need to do an update/erratum for some RIF documents, including [1], where 
   we can include a mention of the SPARQL Entailment Regimes document and rif:usedWithProfile.

The predicate is in the RIF namespace, I presume the RIF WG is o.k. with that (recalling the mailing list discussions there). However, the mechanism itself, ie, the semantics of rif:usedWithProfile, is not SPARQL specific (see [1] below). I wonder whether it is worth separating this into a distinct document that can be referenced to in general as a Rec in its own right.
