//Let the compiler infer an XNamespace: XNamespace customNamespace = "urn:foo";

//Infer a custom namespace with prefix (with + operator overloading): XName customAttributeName = XNamespace.Xmlns + "rx";

//Generate an XAttribute from the above: XAttribute customAttribute = new XAttribute( customAttributeName, customNamespace.NamespaceName );

//Generate a custom element in our namespace (with + operator overloading): XElement custom = new XElement( customNamespace + "custom", "Hello world" );

//Generate an XML document with the namespace declared at document-level: XElement document = new XElement( "root", new Object[] { customAttribute, custom } );

Note: “To enable atomization of XName objects,
the constructor is not public, so you are not able
to directly instantiate an XName object.”
