     <h4>Conveying the icon's meaning to assistive technologies</h4>
-    <p>To ensure that assistive technologies – such as screen readers – correctly convey the meaning of an icon, additional hidden text should be included with the <code>sr-only</code> class, and the icon itself explicitly associated with the form control it relates to using <code>aria-describedby</code>. Alternatively, ensure that the meaning (for instance, the fact that there is a warning for a particular text entry field) is conveyed in some other form, such as changing the text of the actual <code>&lt;label&gt;</code> associated with the form control.</p>

     <p>Although the following examples already mention the validation state of their respective form controls in the <code>&lt;label&gt;</code> text itself, the above technique (using <code>sr-only</code> text and <code>aria-describedby</code>) has been included for illustrative purposes.</p>
