The aria-checked attribute must be placed on the container of each radio button. Its value must be set dynamically ing to the state of the associated radio button: aria-checked="true" when the radio button is selected. aria-checked="false" when the radio button is not selected.

When focus moves to the group in which a radio button is selected, pressing Tab and Shift+Tab keys move focus to the radio button that is checked. Up Arrow and Down Arrow keys move focus and selection. Up Arrow key press moves focus and selection forward through the radio buttons in the group.

In the case of aria-pressed , like most tri-state value types, the default value is undefined . Toggle buttons require a full press-and-release cycle to change their value. Pressing and releasing it once changes the value to true . If it's pressed and released again, the value changes back to false .
