        <p>
            ConfirmPopup component uses <i>alertdialog</i> role and since any attribute is passed to the root element you may define attributes like <i>aria-label</i> or <i>aria-labelledby</i> to describe the popup contents. In addition
            <i>aria-modal</i> is added since focus is kept within the popup.
        </p>
        <p>
            When <i>require</i> method of the <i>$confirm</i> instance is used and a trigger is passed as a parameter, ConfirmPopup adds <i>aria-expanded</i> state attribute and <i>aria-controls</i> to the trigger so that the relation between the
            trigger and the dialog is defined.
        </p>
