A string containing the current xml:lang scope.
This property represents the xml:lang scope within which the current node resides. For example, here is an XML fragment with xml:lang set to US English in the root element:
Example
<root xml:lang="en-us"> <name>Fred</name> </root>
When the reader is positioned on the name element, you can use this property to find that it is in the scope of a US English xml:lang attribute.
