Столкнулся с проблемой корни которой для меня загадка.
Есть XSD который был загружен в расширение и в отладчике прекрасно разворачивается, все данные вставляются корректно, поля верифицируются тоже. Но при записи, половина того что выгружается теряется.

При выгрузке получается следующее

<?xml version="1.0" encoding="UTF-8"?>
<goods-catalog xmlns="http://www.crystals.ru xmlns:xs="http://www.w3.org/2001/XMLSchema xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance
	<bar-code xmlns="" xmlns:d2p1="http://www.crystals.ru code="2000092220018" marked="true" marking-of-the-good="00-00001767">
		<price-entry price="250">
			<begin-date>2024-03-07T00:00:00</begin-date>
			<end-date>2026-03-07T00:00:00</end-date>
			<number>1</number>
		</price-entry>
		<count>0.5</count>
	</bar-code>
</goods-catalog>

Во первых что-то с xmlns... почему-то targetNamespace не отрабатывает, возможно, поэтому по пути goods-catalog/bar-code/price-entry нет записи department а только "простые" типы, а в отладчике видно все поля.

ЧЯДНТ?

на инфостарте ответили.
Я в коде повторно использовал ОбъектXDTO, а так нельзя.
