(PowerBuilder) Create Signed SOAP XML for Albanian Fiscalization Service

Important: This example requires Chilkat v9.5.0.80 or greater.

This example is created for a customer that needs to send signed billing/invoicing SOAP XML requests to http://efiskalizimi-test.tatime.gov.al:80/FiscalizationService

The example demonstrates how to create and signed the SOAP XML message that is to be sent.
