A string value that contains xml:lang context value.
In the example XML below, when the System.Xml.XPath.XPathNavigator is positioned on the name element, the XPathNavigator.XmlLang property returns a scope of en-us indicating that the node is in the scope of a xml:lang="en-us" attribute.
Example
<root xml:lang="en-us"> <name>Name</name> </root>
