-     public class Submit
      extends FormButton

  Render a submit button. The submit tag is used together with the form tag to provide asynchronous form submissions. The submit can have three different types of rendering:
  - input: renders as html <input type="submit"...>
  - image: renders as html <input type="image"...>
  - button: renders as html <button type="submit"...>
  Please note that the button type has advantages by adding the possibility to seperate the submitted value from the text shown on the button face, but has issues with Microsoft Internet Explorer at least up to 6.0
