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    <> ];
                 [ :position 2 ;
                   :value    <> ]

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.
