AX2012 R3 WMDP, Разрешить ввод "<" в поля web-формы (ошибка "A potentially dangerous Request.Form value was detected from the client")

[RSrd]

Доброго дня!

AX2012 R3 Warehouse Mobile Device Portal, IIS 8

Коллеги, есть необходимость разрешить ввод в поля web-формы коды маркировки, иногда содержащие символ "<", т.е. напомишающие html-тэги.

При отправке формы получаем ошибку: "A potentially dangerous Request.Form value was detected from the client"

Как отключить эту валидацию?
Правки web.config не помогают.

Цитата:

A potentially dangerous Request.Form value was detected from the client (IC="<asdf").
Description: ASP.NET has detected data in the request that is potentially dangerous because it might include HTML markup or script. The data might represent an attempt to compromise the security of your application, such as a cross-site scripting attack. If this type of input is appropriate in your application, you can include code in a web page to explicitly allow it. For more information, see http://go.microsoft.com/fwlink/?LinkID=212874.

а в какой-то момент при вводе заменять на &lt &gt - не получится?

[RSrd]

Нет, к сожалению, заменять не получится, потому что нужно сканировать уже наклеенные на товарах коды, в том числе, приходящие от поставщиков.
