static int	ORDERING_MODE_ORDERED The constant indicating that ordered results are to be returned by certain path expressions, union, intersect, and except expressions, and FLWOR expressions that have no order by clause.
static int	ORDERING_MODE_UNORDERED The constant indicating that unordered results are to be returned by certain path expressions, union, intersect, and except expressions, and FLWOR expressions that have no order by clause.
static int	SCROLLTYPE_FORWARD_ONLY The constant indicating that the result sequence can only be scrolled forward.
static int	SCROLLTYPE_SCROLLABLE The constant indicating that the result sequence can be scrolled forward or backward and is insensitive to any updates done on the underlying objects
