+<title>Anonymisation</title>
+
+<p>
+Dans le circuit de traitement d'une demande, après qu'elle ait été traitée,
+il peut être souhaité d'en conserver une trace à des fins statistiques, tout en
+lui retirant toute information à caractère personnel.
+</p>
+
+<p>
+L'élément « Anonymisation » répond à ce genre de besoin; il sera généralement
+placé dans un état du workflow atteint après un expiration d'un délai.
+</p>
+
+<note style="important"><p>
+L'anonymisation des données privées est une obligation légale dans beaucoup de
+situations.
