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

* First create the following XML to be signed.  This can be created programmatically as shown in the code below, or 
* you can simply load the XML to be signed from a file..

* <?xml version="1.0" encoding="utf-8"?>
