It certainly makes sense that they be the same. The order problem has been bothering me, as the testcase result format will need to be able to repesent this if we get ORDER BY. I would prefer the binding results to not be in a rdf list due to the difficulty of processing the graph, and sequences seem to be unfashionable. Are structures like: [] :list [ :position 1 ; :value <http://foo.example.com> ]; [ :position 2 ; :value <http://bar.example.com> ] equally unpopular? Its my current preferred fix. The schema and results files can be modified quite simply to represent order in this way, and its easy to query. The other thing that the result format cant represent is the order of the columns, which is probably less of an issue, but rq23 does say something about it, as the XML result format can distinguish. - Steve
