  @brief Sample XLMAP Data hook program
  @details This hook script should NOT be modified in place, as the changes
    would be lost in your next Data Controller deployment.
    Instead, create a copy of this hook script and place it OUTSIDE the
    Data Controller metadata folder.

  Available macro variables:
    @li DC_LIBREF - The DC control library
    @li LIBREF - The library of the dataset being edited (is assigned)
    @li DS - The target dataset being loaded
