Комментарии

Если в коллекции уже имеется атрибут с таким же именем, исходный атрибут удаляется из коллекции и node добавляется в начало коллекции.If an attribute with the same name is already present in the collection, the original attribute is removed from the collection and node is added to the beginning of the collection.
