XML : How to write xsd:schema tag using XmlDocument

I'm trying to write a XML-document programatically.

I need to add <xsd:schema> tag to my document.

Currently I have:

  var xmlDoc = new XmlDocument();    var root = xmlDoc.CreateElement("root");  xmlDoc.AppendChild(root);    var xsdSchemaElement = xmlDoc.CreateElement("schema");  xsdSchemaElement.Prefix = "xsd";  xsdSchemaElement.SetAttribute("id", "root");    root.AppendChild(xsdSchemaElement);    

However, this renders to:

  <root>    <schema id="root" />  </root>    

How do I get the tag to be <xsd:schema>?

Already tried var xsdSchemaElement = xmlDoc.CreateElement("xsd:schema"); which simply ignores the xsd:.

Edit #1

Added method

  private static XmlSchema GetTheSchema(XmlDocument xmlDoc)  {      var schema = new XmlSchema();      schema.TargetNamespace = "xsd";      return schema;  }    

which is called like xmlDoc.Schemas.Add(GetTheSchema(xmlDoc)); but does not generate anything in my target XML.
