/*
 * Inscoper NBO Example: Import NBO-XML
 * ====================================
 * This example demonstrates how to populate an NBO object tree from an XML string
 * or from an XML file, and how imported documents are validated.
 *
 * Prerequisites:
 * -------------
 * 1. Installation: inscoper-nbo-<version>.jar must be on the classpath.
 * 2. Sample Data: this example reads instrument_sample.xml. Change SAMPLE_PATH
 *    below to the location where you saved it.
