How to Fix the Problem

Use “aria-” attributes according to the WAI-ARIA specification

The Algorithm, in Simple Terms

The engine is searching for attributes using the “aria-” prefix which do not match the WAI-ARIA specification. For example aria-dontexsist=“true”

Why Is it Important?

Users who use assistive tools, such as screen readers rely on exposure of the states and properties to understand the context, such as a radio button selected, an invalid form field. Exposing the state and properties attributes enables users to understand the widget and how to interact with it.

Code Example

<li id="id_example_bold1"  
class="example_toggleButton"
role="button"
tabindex="0"
aria-pressed="false"
aria-labelledby="bold_label"
aria-controls="text1">
<img src="/example_"http://www.oaa-accessibility.org/media/examples/images/button-bold.png" alt="example_bold text" align="middle">
</li>
