   Öntanımlı harici öğe yükleyiciyi değiştirir. İlgili işlem için
   <constant>LIBXML_NOENT</constant> atanmış olsa bile, XXE saldırılarını
   önlemek için isteğe bağlı harici öğe yüklenmesini engellemekte
   kullanılabilir ve genellikle
   <function>libxml_disable_entity_loader</function> çağrısına tercih edilir.
