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

// The signed XML to be verified in this example contains the following:

// <?xml version="1.0" encoding="ISO-8859-1"?>
// <DTE version="1.0" xmlns="http://www.sii.cl/SiiDte">
// <Documento ID="F13T34">
// ...
// </Documento>
// <Signature xmlns="http://www.w3.org/2000/09/xmldsig#">
// ....
// </Signature>
// </DTE>

// Load the signed XML into sbXml -- telling Chilkat to interpret the bytes as iso-8859-1
