2009-05-07 15:07:08: Sub-issue here:
Do we allow some variables not grouped/aggregated and what is the behavior of that. E.g. a variation of Andy's example (http://jena.hpl.hp.com/~afs/SPARQL-F2F1-AFS.pdf, slide 9):
SELECT ?name
{
{ SELECT ?x
{ ?x foaf:knows?y . ?z a foaf:Person}
GROUP BY ?x
HAVING (count(?y) > 10)
}
?x foaf:name?name
}
