205 документа используется навигатор C<IMPL::DOM::Navigator::Builder> для

206 сопоставления схемы и свойств преобразуемого объекта. Элементы полученного

207 документа имеют ссылки на соответствующие им элементы схемы.

217 C<NavigateCreate> для создания элемента соответсвующего свойству объекта,
0f59b2de72af *fixed IMPL::DOM::Schema circular module references
sergey
parents: 257
diff changeset
218 затем вызывается метод C<Transform> для преобразования значения свойства, при
0f59b2de72af *fixed IMPL::DOM::Schema circular module references
sergey

diff changeset
219 этом C<currentNode> указывает на только что созданный элемент документа.
