Poznámky

Tato vlastnost představuje xml:lang obor, ve kterém se nachází aktuální uzel. Tady je například fragment XML s xml:lang nastavenou na angličtinu USA v kořenovém elementu:

<root xml:lang="en-us">

<name>Fred</name>

</root>

Při umístění čtenáře name na prvek můžete tuto vlastnost použít k vyhledání, že je v oboru atributu USA v angličtině xml:lang .
