Description:
------------
To validate a dataset, I try to generate a XML-Schema with the help of an database-definition. The Schema-file is correctly build. XMLSpy works with it fine... but if I try to run the same files with php, php reports a failure.



Reproduce code:
---------------
test.php:
#!/wir/webadmin/share/php504/bin/php
<?

$xml = new DOMDocument(); 
$xml->load('gd.xml'); 
if ($xml->schemaValidate("gd.xsd")) { 
     echo "Validated OK"; 
} else { 
     echo "Validate FAILED"; 
} 

?>
--------------------------------------------
gd.xml:
<?xml version="1.0" encoding="iso-8859-1"?>
<!-- edited with XML Spy v4.4 U (http://www.xmlspy.com) -->
