Definition of SPARQL variable pre-binding

Hi, (this question is motivated by the ongoing Data Shapes WG, but I don't speak on their behalf). Jena and other APIs such as Sesame support the concept of pre-binding variables prior to SPARQL execution, using QueryExecution.setInitialBinding(). This is convenient to reuse parameterized q
