 * <p/> <b>Examples</b>
 * <p/>
 * <!-- START SNIPPET: exdescription -->
 * In this example, a radio control is displayed with a list of genders. The gender list is built from attribute
 * id=genders. The framework calls getGenders() which will return a Map. For examples using listKey and listValue attributes,
 * see the section select tag. The default selected one will be determined (in this case) by the getMale() method
 * in the action class which should retun a value similar to the key of the getGenters() map if that particular
 * gender is to be selected.<p/>
