"""Génération du bulletin en format XML


Note: la structure de ce XML est issue de (mauvais) choix historiques
et ne peut pas être modifiée car d'autres logiciels l'utilisent (portail publication
bulletins etudiants).

Je recommande d'utiliser la version JSON.
Malheureusement, le code de génération JSON et XML sont séparés, ce qui est absurde et
complique la maintenance (si on ajoute des informations aux bulletins).
