/*
 * Inscoper NBO Example: Export NBO-XML
 * ====================================
 * This example demonstrates how to serialize an NBO object tree to an XML string
 * or to an XML file, and how validation is applied on export.
 *
 * Prerequisites:
 * -------------
 * 1. Installation: inscoper-nbo-<version>.jar must be on the classpath.
