Description:
------------
I'm trying to validate a SMIL document using DOMDocument and the official w3c schema.

The validation fails throwing several warnings.


Reproduce code:
---------------
<?

$smil = "<smil xmlns=\"http://www.w3.org/2001/SMIL20/Language\">
<head>
 <layout>
  <region id=\"schermo\" width=\"100%\" height=\"100%\" left=\"0\" top=\"0\" />
 </layout>
</head>
<body>
 <par>
  <img src=\"cid:star1.jpg\" region=\"schermo\" />
 </par>
 <par>
  <text src=\"cid:testo\" region=\"schermo\" />
 </par>
</body>
</smil>";


$docSmil = new DOMDocument();
if (! $docSmil->loadXML($smil, LIBXML_NOCDATA)) {
        throw new Exception("The SMIL file is not a valid xml document");
}

if (! $docSmil->schemaValidate('http://www.w3.org/2001/SMIL20/smil20.xsd')) {
        throw new Exception("IThe SMIL file is not a valid SMIL document");
}
echo "OK\n";
?>


Expected result:
----------------
OK

Actual result:
--------------

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions.  Due to the volume
of reports we can not explain in detail here why your report is not
a bug.  The support channels will be able to provide an explanation
for you.

Thank you for your interest in PHP.
