    //  This example requires the Chilkat Crypt API to have been previously unlocked.
    //  See Unlock Chilkat Crypt for sample code.

    //  An HTTP SOAP request is an HTTP request where the SOAP XML composes the body.
    //  This example demonstrates how to add a WS-Security header such as the following:
    // 
    //  <wsse:UsernameToken xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" wsu:Id="SecurityToken-6138db82-5a4c-4bf7-915f-af7a10d9ae96">
    //    <wsse:Username>user</wsse:Username>
    //    <wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordDigest">CBb7a2itQDgxVkqYnFtggUxtuqk=</wsse:Password>
    //    <wsse:Nonce>5ABcqPZWb6ImI2E6tob8MQ==</wsse:Nonce>
    //    <wsu:Created>2010-06-08T07:26:50Z</wsu:Created>
    //  </wsse:UsernameToken>
    // 

    //  First build some simple SOAP XML that has some header and body.
