LINQ to XML makes this trivial - you just specify the namespace for the element, and it will include the xmlns="..." automatically. You can give it an alias, but that's slightly harder. To produce the exact document you've shown, you just need:

XNamespace ns = "http://s3.amazonaws.com/doc/2006-03-01/";
var doc = new XDocument(
    new XElement(ns + "VersioningConfiguration",
       new XElement(ns + "Status", "Enabled")));
Console.WriteLine(doc);

LINQ to XML is by far the best XML API I've used, particularly in its handling of namespaces. Just say no to XmlDocument :)
