A simple program

<?xml version="1.0" encoding="UTF-8"?>
<!-- Interpreter type can be forced through the @interpreterType attribute -->
<xsh:program interpreterType="bash" xmlns:xsh="http://xsd.nore.fr/xsh">
	<xsh:functions>
		<!-- This will include ns_realpath function definition --> 
		<xi:include href="relativepath/to/filesystem.xsh"

	<!-- The program body -->
