Comentários

Observação

A partir do .NET Framework 2.0, recomendamos que você crie XmlReader instâncias usando o XmlReader.Create método para aproveitar a nova funcionalidade.

Essa propriedade representa o xml:lang escopo no qual reside o nó atual. Por exemplo, aqui está um fragmento XML com xml:lang definido como inglês dos EUA no elemento raiz:

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

<name>Fred</name>

</root>

Quando o leitor está posicionado sobre o name elemento, você pode usar essa propriedade para descobrir que ela está no escopo de um atributo em inglês xml:lang dos EUA.
