 Based on the order in which the windows are defined in the window clause, forward and backward window references are permitted. In other words, a window may use any other window defined in the `<window_expression>` that it is part of, as `reference_window_name`, irrespective of the order of which they are defined. Cyclic references and using multiple window references in a single window are not allowed.
 
-The scope of the new window_name of a defined window contained in a `<window_expression>` consists of any window definition that are part of the `<window_expression>`, together with the SELECT clause of the `<query_specification>` or `<SELECT statement>` that contains the window clause. If the `<window_expression>` is contained in a `<query_specification>` that is part of `<query_expression>` which is a simple table query, then the scope of the new window_name also includes the `<order_by_expression>`, if any, of that `<query_expression>`.
