How to unload a section property from 1s?

Question

1C-Bitrix

When importing Bitrix, it is possible to import section properties into the site structure in the following format (in an xml file):

<Группы>
        <Группа>
            <Ид>40a1ea23-db7d-4040-9fd2-c2ee4c742ckk</Ид>
            <НомерВерсии>123</НомерВерсии>
            <ПометкаУдаления>false</ПометкаУдаления>
            <Наименование>Тетради</Наименование>
            <ЗначенияСвойств>
                <ЗначенияСвойства>
                    <Ид>UF_NAME</Ид>
                    <Значение>Другое имя</Значение>
                </ЗначенияСвойства>
                <ЗначенияСвойства>
                    <Ид>UF_DESCRIPTION</Ид>
                    <Значение>Другое описание</Значение>
                </ЗначенияСвойства>
            </ЗначенияСвойств>
        </Группа>
    </Группы>

Here I added the parameters manually. Where in the nomenclature structure can these properties be added and how can they be uploaded to the site? <ЗначенияСвойств> ... </ЗначенияСвойств>
