        <h5>Accessibility</h5>
        <h6>Screen Reader</h6>
        <p>
            Rating component internally uses radio buttons that are only visible to screen readers. The value to read for item is retrieved from the <router-link to="/locale">locale</router-link> API via <i>star</i> and <i>stars</i> of the
            <i>aria</i> property.
        </p>

        <h6>Keyboard Support</h6>
        <p>Keyboard interaction is derived from the native browser handling of radio buttons in a group.</p>
