history:

- we tried to get this into "RIF RDF and OWL Compatibility" first, but it was too late at that time in the process of RIF.
- then it emerged into the RIF-in-RDF document, which, however from RIF's point of view will only go to Note status at max.
- there were some discussions whether we as SPARQL could complete that spec and take it to Rec, but that appeared too much on our own plate, ie adding 
  another rec track document, so we decided to leave it in the entailment regimes doc. 

that's the current status.


> Your small spec does not seem to depend on it, other than referring to that as one possibility (which can be done non-normatively). It refers to RIF-and-RDF which is closed and published.

yes, "RIF RDF and OWL Compatibility"  although it would be IMO a better place can't really be touched without the RIF WG anymore, so that option is out, yes.

> Ie, I do not see the dependency issue.

no real dependency other than what I put now in the sparql doc is a stripped down version to what we had in the editor's draft of RIF-in-RDF, see

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.
