REGS doesn't have variables or do bindings. It returns subgraphs, and
is primarily aimed at resource discovery where the query identifies
resources bound to the root node of the query template, and a subgraph of
all properties for those resources is returned, which can be processed by
subsequent queries or other RDF applications as needed.
