Translate the following English sentence to French:
"Such voluntary information on area of origin is possible, as long as protected designations of origin are not involved, because it logically follows that protected designations of origin must be protected as such."
C'est envisageable, à condition qu'il ne s'agisse pas d'appellations d'origine contrôlées, parce que celles-ci doivent évidemment être protégées.
