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

// Create the following pre-signed SOAP XML:
// Note: We'll be constructing a placeholder for the wseBinarySecurityToken in the soapenv:Header.
// Chilkat will automatically replace the "BinarySecurityToken_Base64Binary_Content" with actual data when signing the XML.

// However: Your application should insert the actual desired timestamp values for wsu:Created and wsuExpires
// Typically this is the current system date/time and a few minutes from the current system date/time.
// The example below shows a 5 minute window.  We'll write code below to insert the current date/time and the current date/time + 5 minutes..
