Cette extension utilise en particulier des XClasses, qui permettent de surcharger le comportement du noyau Typo3,
mais qui induisent par ailleurs un certain risque de conflit en cas de mise à jour de Typo3.

> A propos des XClasses: <https://docs.typo3.org/m/typo3/reference-coreapi/master/en-us/ApiOverview/Xclasses/Index.html>
