      - hook_<libraryPrefix>_addEnableRuleDpes()
        Determines the data point elements that are additionally called for rule evaluation for the setting of an elementary symbol to inactive/active.
      - hook_<libraryPrefix>_addHighlightRuleDpes()
        Determines the data point elements that are additionally used for rule evaluation in order to set an elementary symbol to highlighted/not highlighted.
      - hook_<libraryPrefix>_addVisibleRuleDpe()
        Determines the data point elements which are additionally used for the rule evaluation in order to set an elementary symbol to visible/invisible.
      - hook_<libraryPrefix>_alterInfoAreaDisplay()
        This function allows the icon-ID, and therefore the icon displayed in an information area, to determine when the value of the data point element that is connected to an information area changes. Which data point elements are connected to a certain information area is determined via the function hook_<LibName>_getInfoAreaDPEs().
      - hook_<libraryPrefix>_fillPopUpMenu()
        This function is used to change the context menu of a symbol or an elementary symbol.
      - hook_<libraryPrefix>_getAlertElement()
        By using this function, the library creator can define were the sum alert of a DPT/DP is located.
      - hook_<libraryPrefix>_getInfoAreaDPEs()
        This function determines the data point elements that can change the icon for an information area of a symbol. For detailed information, see also hook_<libraryPrefix>_displayInfoAreaIcon() and hook_<libraryPrefix>_alterInfoAreaDisplay().
      - hook_<libraryPrefix>_getInvalidElement()
        This function determines the data point element that indicates whether a data point is invalid.
      - hook_<libraryPrefix>_getOperationModeElement()
        This function determines the data point node that saves the operating states.
      - hook_<libraryPrefix>_hasDpeAnActiveAdress()
        This function is used to check whether an elementary symbol in a faceplate has a peripheral address.
      - hook_<libraryPrefix>_libEnableElementarySymbol()
        This function returns TRUE when a certain data point element is activated.
      - hook_<libraryPrefix>_libHighlightElementarySymbol()
        This function returns TRUE when a certain data point element is highlighted.
      - hook_<libraryPrefix>_libVisibleElementarySymbol()
        This function returns TRUE if a certain data point element is visible.
