Usually a check box is presented as a rectangle that contains a check mark when it is selected and is empty
when deselected. However a check box can have three states, often represented by a check mark, a cross,
and emptiness. A radio button can only have two states, which are often presented as a circle that is filled
(or "illuminated") when the button is selected and empty when deselected.
A field with a checkBox user interface can have at most one items child. The items list can have at most
three values. The first value in the list is the "on" value, that is the value taken when the button or box is
selected. If there is a second value, it is the "off" value, that is the value taken when the button or box is
deselected. If there is a third value, it is the "neutral" value, that is the value taken when the check box is
empty. If a third value is provided for a radio button it is ignored. When the second or third value is not
provided it defaults to the null string.
