RadioButton 

The RadioButton UI element is a button with two states (on/off) that enables users to select options. The RadioButton UI element allows you to spread the displayed radio buttons individually on the screen instead of grouping them in a table. You can toggle the radio button when you bind the UI elements to the same context attribute.

The radio button is selected if the context attribute to which the selectedKey property is bound, contains the value of the key that belongs to this radio button. The key is specified by the keyToSelect property.

To enable the development of accessible applications, the tooltip property is checked during the syntax check if the properties text and label are not set.

A tooltip does not necessarily have to be set for this UI element, but it could make sense to set it if it contains detailed semantic information.
