I'm not sure which way round you mean "multiple valid resultsets per query": the vocabulary allows multiple solutions per result table. And also multiple result sets per result graph because it is rooted from a single node. The example uses <> as that node but there is no reason it has to be that; you could have a bNode there, and have another starting bNode somewhere else. Could you give an example of when there would be multiple result sets? I can image a "query request" to actually consist of a series of "queries" all of which should be executed.
