After considering what material to put in rq23 and how to record the 
discussions and conclusions in all the email, I propose that the interested 
parties prepare a separate WG note (or, alternatively, a member submission).

I will include some text that explains SPARQL at the level of simple 
entailment because the point of rq23 is to say what SPARQL/Q is, not what it 
might be.  It is confusing to have all the possible options outline when they 
don't apply to this version of SPARQL.

The only other thing I think we might consider is an appendix that expands on 
the definitions section but again I think it should stick to what this SPARQL is.

There a lot to be said for a separate document in that it can evolve 
independently of rq23 (and the rec track process).
