The intrinsic Radio control allows a user to select one choice from a number of options. Radio controls are also called option buttons. Radio controls can be grouped by using the same NAME attribute.
| NAME | A string representing the name of the Radio control |
| VALUE | A string representing the value of the control when submitted (each radio button should have a unique value) |
| CHECKED | An option that causes the Radio control to be selected by default |
| OnClick | Fires when the control is clicked |
| OnFocus | Fires when the control receives the focus |
