DISTINCT is a modifier that happens after the expressions have been > evaluated and the nre variables bound. http://lists.w3.org/Archives/Public/public-rdf-dawg/2009OctDec/0585.html A discussion of the order of modifers hasn't made the doc yet but it's: pattern => group inc aggregate calculation => extends => having => order by => project => distinct => reduced => offset/limit So, the names are out of scope earlier ones (GROUP BY) and legal in later ones (e.g. ORDER BY and DISTINCT).
