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

* See: Apply 2nd Signature to sii.cl Factura Electr�nica (Chile Servicio de Impuestos Internos)
* for an example showing how to apply a 2nd signature.

* We want to sign XML that looks like the following:
