  80 /*  [Description]
  81
  82     In each SFx application one instance of the SfxBindings-Class will
  83     exists from <SfxApplication::Init()> until <SfxApplication::Exit()>.
  84     This instance is automatically created and destroyed by SfxApplication.
  85     However these instances will be handled by the Macro <SFX_BINDINGS>
  86     or the associated <SfxViewFrame>.
  87
  88     The SfxBindings manages all of its Slot-Ids bound by the registerd
  89     controllers and keeps a cache of the <Slot-Server> respectively.
  90     (it is what we call the combination of SfxShell instance and SfxSlot).
  91     In the SfxBindings it is stored, if and in this case which controllers
  92     that are dirty and which Slot-Server-Caches are dirty respectively.
  93     It summarizes status queries (calls to the status methods specified
  94     in the IDL) that are served by the same state methods, and handles
  95     the simulation of <Pseudo-Slots>.
