/**
    Defines how bulk update may be done on Graphs.
<p>
    Bulk updates are not necessarily transactions; that is, a bulk update may
    fail part-way through, leaving some but not all triples added or deleted.
    However, if a bulk update does not fail (ie throw an exception) then the
    addition or removal of triples must have been successfully completed
    in accordance with the operation of the owning graph.
