Regarding sec 10.1 "BIND: Assigning to Variables": http://www.w3.org/TR/sparql11-query/#bind What happens if the same variable is bound more than once using BIND? For example: PREFIX dc: <http://purl.org/dc/elements/1.1/> PREFIX ns: <http://example.org/ns#> SELECT ?title ?price { BIND (?title as "The World") BIND (?title as "The Universe") ?x dc:title ?title ; ns:price ?p . } Should this be handled as: - an error? - both bindings are used (to produce multiple solutions)? - The first or last BIND statement for ?title takes precedence? It would be helpful to clarify this in the spec.
