Send soap request

Hello,

I have a problem with sending soap request.

I get wsdl . The wsdl class bellow

Class Data.SOAP.PrinServ.NotificationRequest Extends (%RegisteredObject, %XML.Adaptor) [ ClassType = "", CompileAfter = Data.SOAP.PrinServ.Lang, Inheritance = right, ProcedureBlock ]
{

Parameter ELEMENTQUALIFIED = 1;

Parameter NAMESPACE = "http://tempuri.org/";

Parameter XMLNAME = "NotificationRequest";

Parameter XMLSEQUENCE = 1;

Property IIN As %String(MAXLEN = "", XMLNAME = "IIN");

Property AccountList As list Of %String(MAXLEN = "", XMLITEMNAME = "string", XMLNAME = "AccountList", XMLPROJECTION = "COLLECTION");

}

The code:
s rq=##class(Data.SOAP.PrinServ.PrintPdfSoap).%New()
set BaseInfo=##class(Data.SOAP.PrinServ.NotificationRequest).%New()
s BaseInfo.IIN=IIN

d BaseInfo.ColvirAccountList.InsertObject(Account)

s rp=##class(Data.SOAP.PrinServ1.PrintResponse).%New()
s rp=rq.PrintNotification(BaseInfo)

my request is missing tag  <string xsi:type="s:string">TESTKZ</string>

<?xml version="1.0" encoding="UTF-8" ?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV='http://schemas.xmlsoap.org/soap/envelope/' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns:s='http://www.w3.org/2001/XMLSchema'>
    <SOAP-ENV:Body>
        <PrintNotification xmlns="http://tempuri.org/">
            <Request xmlns:s01="http://tempuri.org/" xsi:type="s01:NotificationRequest">
                <IIN xsi:type="s:string">1234567910</IIN>
                <AccountList xsi:type="s:string">TESTKZ</AccountList>
            </Request>
        </PrintNotification>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

The correct request:

<?xml version="1.0" encoding="UTF-8" ?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV='http://schemas.xmlsoap.org/soap/envelope/' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns:s='http://www.w3.org/2001/XMLSchema'>
    <SOAP-ENV:Body>
        <PrintNotification xmlns="http://tempuri.org/">
            <Request xmlns:s01="http://tempuri.org/" xsi:type="s01:NotificationRequest">
                <IIN xsi:type="s:string">1234567910</IIN>
                <AccountList>
                    <string xsi:type="s:string">TESTKZ</string>
                </AccountList>
            </Request>
        </PrintNotification>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>
