   extension is controlling the value (<code>levelOfControl</code> will be set to
   "controlled_by_other_extensions"). The <code>set()</code> call will succeed,
   but the setting will be immediately overridden. As this might be confusing, it
   is advisable to warn the user when the settings they've chosen aren't
   practically applied.

   This means that you ought to use the <code>get()</code> method to determine
   your level of access, and then only call <code>set()</code> if your extension

   reduce user confusion):
