A GNVL is displayed in an editor view (NVL Editor), however cannot be modified by the
user. It just shows the current content of the corresponding GVL, i.e. if you change the
basic GVL, the GNVL will be updated accordingly.
Automatically a comment is added at top of the declaration part of a GNVL, providing
information on the sender (device path), the GVL name and the protocol type.
