 * 
 * A select list option is a single option in a drop down list on any of the
 * forms. The option has a value which must be used to send the option value
 * to the server action and a name, which is displayed to the user while
 * choosing the option. The name of the option is already internationalized
 * by the server before sending the data block to the ui so that no additional
 * resource lookup is required before displaying the options to the user.
 * 
 * Since this object, on the ui side, is meant for display only the values
 * are maintained as simple strings. If at all required, each form validator
 * needs to convert the string to a true type if required.
