Remarques
TermSetItem est une classe abstraite et doit être substitué. Il contient des références aux parties qui définissent un TaxonomyItem (par exemple, nom, Id, etc.). Aussi, il constituée une collection d'objets de Term enfants et fournit l'interface pour récupérer ou mettre à jour les objets de Term enfants. Si l' TermSetItem est un mot clé ou un orphelin, il ne doit pas avoir d'enfants.
Chaque TermSetItem possède un utilisateur associé en tant que propriétaire. Il a un indicateur indiquant si elle peut être utilisée dans l'interface utilisateur de marquage. Il dispose également d'un CustomSortOrder champ définit l'ordre de tri des termes enfant.
