XML验证:验证根没有匹配的全局声明

我创建了一个XML文件，但是当我试图对XSD进行验证时，我一直得到以下错误:

错误1845:元素"{http://www.stormware.cz/schema/version_2/data.xsd} dataPack":验证根没有匹配的全局声明。

PHP 5.4.7 . libxml 2.7.8.

我的函数:

public function validateXml($dokument){
    // Enable user error handling
    libxml_use_internal_errors(true);
    $xml = new DOMDocument();
    $xml->load($dokument);
    $tempFile = time() . '-' . rand() . '-document.tmp';
    $xml->save($tempFile);
    $tempDom = new DOMDocument();
    $tempDom->load($tempFile);
    // Delete temporary file.
    if (is_file($tempFile))
    {
        unlink($tempFile);
    }

    if (!$tempDom->schemaValidate('order.xsd')) {
        print '<b>DOMDocument::schemaValidate() Generated Errors!</b>';
        $this->libxml_display_errors();
    }
}

我的XSD文件:www.stormware.cz/模式/version_2/data.xsd

My XML file:
