Attribute aria-polite not allowed on element a at this point

Question

I have this html code:

<a href="https://twitter.com/twitterapi" class="twitter-timeline" data-widget-id="X" data-theme="dark" data-chrome="transparent" data-tweet-limit="1" aria-polite="polite">Tweets by @twitterapi</a>

But when I try to validate this code with http://validator.w3.org/ it shows me this error:

"Attribute aria-polite not allowed on element a at this point"

Anyone have a clue?

Thanks in advance.

Answer 1

There is no aria-polite attribute.

Maybe you mean the aria-live attribute with the value polite?
