How to write saml token to XML without SubjectConfirmationData

Hi,

  I would like to serialize saml token to XML and I am using that code:

if (handler.CanWriteToken)
            {
                var sb = new StringBuilder();
                handler.WriteToken(new XmlTextWriter(new StringWriter(sb)), token);
                return sb.ToString();
            }

It works ok but I would like to ignore SubjectConfirmationData node, so I wouldn't like to write attributes like Recipient, InResponseTo etc in this XML representation of token.

Is there any way to do this? I tried to override method in Saml2SecurityTokenHandler:

protected override void WriteSubjectConfirmationData(XmlWriter writer, Saml2SubjectConfirmationData data)
        {
            //base.WriteSubjectConfirmationData(writer, data);
        }

but after that it's still works the same, so this section is added also to XML.

Thanx for any help.
