+/*
+	Requires PHP5, uses built-in DOM extension.
+	To be used in PHP4 scripts using DOMXML extension: allows PHP4/DOMXML scripts to run on PHP5/DOM.
+	(Optional: requires PHP5/XSL extension for domxml_xslt functions, PHP>=5.1 for XPath evaluation functions, and PHP>=5.1/libxml for DOMXML error reports)
+
+	Typical use:
+	{
+		if (PHP_VERSION>='5')
+			require_once('domxml-php4-to-php5.php');
+	}
