The inline message is placed below the radio buttons. The user can select only one radio button. The name attribute on messageRadioSet must be set for this purpose. To add a component after the radio buttons, use the end named child

Use the required attribute to specify that user input is required. An asterisk displays next to the prompt when user input is required. Use the selectedIndex and selectedValue attributes to specify the index and value of the globally selected item, respectively.

In addition to general and message attributes, you can also set the primaryClientAction attribute to fire an event when the user selects an item.
