This display element is used to display a boolean value on the screen and/or get a boolean value entered by the user.
<Value> (non-repetitive boolean element): The displayed/entered boolean value. Access it (to set its initial value or to retrieve the value that has been entered by the user) through a reference to the parent Check Box element or to a higher level display element containing it.
You may add an action sub-model named <On Change> to model what should be done when the user clicks the check box (thus changing the value). If you don't, nothing is done until another user action causes some action to be performed (e.g. pressing a Button).
