Not sure why you consider this wrong. It has the right xmlns attributes, it just differs in the namespace, but that shouldn't be a problem.

This topic could also be of use. It describes adding a namespace.

I found out outsystem generate the request as soap version 1.2 when the server expect us to send 1.1

note outsystems didn't ask me which version should I use and I don't see any option to do that.

is there any way to do that without writing a custom extension

I found the issue and solved it :)

The solution basically. I need to create  custom extension to sign The request.

so I take the code in this article and use it as a base for my extension. 

this is the code I did to solve this issue :)

public void MssSetupCertificateAuth(byte[] ssServerCertificateContent, byte[] ssClientCertificateContent, string ssCertificatePassword)

        {

            ISOAPClient client = SoapRequest.GetCurrentClient();

            var clientCert = new X509Certificate2(ssClientCertificateContent, ssCertificatePassword);

            var serverCert = new X509Certificate2(ssServerCertificateContent);

            //X509Certificate2 serverCert = GetCertificateFromStore("ef23d67f06681fde8d67cc7c485293de636e3311");

            // configure binding to accept certificates

            client.Endpoint.Binding = GetCustomBinding();

            client.ClientCredentials.ClientCertificate.Certificate = clientCert;

            client.ClientCredentials.ServiceCertificate.DefaultCertificate = serverCert;

            client.Endpoint.Contract.ProtectionLevel = System.Net.Security.ProtectionLevel.Sign;

        }

 private System.ServiceModel.Channels.Binding GetCustomBinding()

        {

            var transpor = new HttpsTransportBindingElement();

                transpor.RequireClientCertificate = true;

            var textMessageEncoding = new TextMessageEncodingBindingElement();

            TextMessageEncoding.MessageVersion = MessageVersion.Soap11;

            var version = MessageSecurityVersion.WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10;

            var security =  SecurityBindingElement.CreateMutualCertificateBindingElement(version, true);

            return new CustomBinding(security, textMessageEncoding, transpor);

        }
