xml — PHP: различное поведение XSLT-процессора в Windows WRT и Linux

У меня есть этот фрагмент PHP-кода:

$xsltPath = $argv[1];
$xmlPath = $argv[2];

$xslt = file_get_contents($xsltPath);
$xml = file_get_contents($xmlPath);

$templateCMSObj = new \DOMDocument();
$templateCMSObj->loadXML($xslt);
$ekbXMLObj = new \DOMDocument();
$ekbXMLObj->loadXML($xml);
$proc = new \XSLTProcessor();
$proc->importStylesheet($templateCMSObj);
$html = $proc->transformToXML($ekbXMLObj);
echo($html);
exit;

Который просто применяет XSLT к данному документу XML.

Когда я применил приведенный ниже XSLT к тому же документу XML, я получил другое поведение Windows по сравнению с Linux-версией PHP.

Вот подробности о версии php и libxml:

Вывод Linux
Это желаемый результат, который на самом деле является результатом применения XSLT в Linux:

<?xml version="1.0"?>
<ns:flat_pallet xmlns:ns="http://new.webservice.namespace" tipo="">
<ns:riferimento_oi labelPath="Standard{0}/Standard{0}" unitIndex="1">
<ns:tipo>Standard</ns:tipo>
<ns:natura_OI>
<ns:UNI>2.1</ns:UNI>
</ns:natura_OI>
</ns:riferimento_oi>
<ns:riferimento_oi labelPath="Standard{0}/Standard{1}" unitIndex="2">
<ns:tipo>Standard</ns:tipo>
<ns:natura_OI>
<ns:UNI>2.2</ns:UNI>
</ns:natura_OI>
</ns:riferimento_oi>
<ns:riferimento_oi labelPath="Standard_due{0}/Standard{0}" unitIndex="1">
<ns:tipo>Standard</ns:tipo>
<ns:natura_OI>
<ns:UNI>2.1</ns:UNI>
</ns:natura_OI>
</ns:riferimento_oi>
<ns:riferimento_oi labelPath="Standard_due{0}/Standard_due{0}" unitIndex="1">
<ns:tipo>Standard_due</ns:tipo>
<ns:natura_OI>
<ns:UNI>2.2</ns:UNI>
</ns:natura_OI>
</ns:riferimento_oi>
</ns:flat_pallet>

Выход Windows
Это неправильный результат производит на Windows:

<?xml version="1.0"?>
<ns:flat_pallet xmlns:ns="http://new.webservice.namespace" tipo="">
<ns:riferimento_oi labelPath="Standard{0}/Standard{0}" unitIndex="1">
<ns:tipo>Standard</ns:tipo>
<ns:natura_OI>
<ns:UNI>2.1</ns:UNI>
</ns:natura_OI>
</ns:riferimento_oi>
<ns:riferimento_oi labelPath="Standard{0}/Standard{1}" unitIndex="2">
<ns:tipo>Standard</ns:tipo>
<ns:natura_OI>
<ns:UNI>2.2</ns:UNI>
</ns:natura_OI>
</ns:riferimento_oi>
<ns:riferimento_oi labelPath="Standard_due{NaN}/Standard{0}" unitIndex="1">
<ns:tipo>Standard</ns:tipo>
<ns:natura_OI>
<ns:UNI>2.1</ns:UNI>
</ns:natura_OI>
</ns:riferimento_oi>
<ns:riferimento_oi labelPath="Standard_due{NaN}/Standard_due{NaN}" unitIndex="">
<ns:tipo>Standard_due</ns:tipo>
<ns:natura_OI>
<ns:UNI>2.2</ns:UNI>
</ns:natura_OI>
</ns:riferimento_oi>
</ns:flat_pallet>

Проблема заключается в использовании NaN вместо относительного индекса: это, безусловно, связано с элементом xsl: number, но я не могу понять, как это исправить …

Путем изменения xsl:number count приписывать * вместо node() шаблон xslt работает как положено как в Win, так и в Linux.
