This XACML validator takes the XACML 2.0 or 3.0 schema and uses it to validate the syntax of a XACML policy you can paste hereafter. Validation is merely done using the schema through the DOMDocument object in PHP.
None of the policies submitted on this website are stored anywhere.

LoadXML($source);
//Validate the XML file against the schema
$valid = $xdoc->schemaValidateSource(file_get_contents($xmlschema));
if ($valid) $not=””;
?>

	<?=$source?>
