Nu SOAP поддерживает стиль документа / литерал?

Question

Я пытаюсь создать веб-сервис, используя стиль документа и использование буквального переноса, но это не работает, я всегда получаю результат с пустым значением, это проблема с Nu SOAP?

Документ WSDL: Стиль документа Использование Literal Wrapped
