2.2.3.4 Window-Created PDU (OD_WND_CREATED)
The Window-Created PDU (OD_WND_CREATED) is sent by the sharing manager to notify participants that a window was created or updated. Every window MUST be associated with an application. The window MUST have a corresponding unique ID, and subsequent updates for that window data MUST come as Window-Created PDUs with the same ID (as specified in section 3.2.5.1.4).
