aria-roledescription is not a label
It is an alternative expression of the Aural UI of the role of an element.
inappropriately using aria-roledescription may inhibit users’ ability to understand or interact with an element.
ARIA 1.1
The wrong way to use aria-roledescription and call out someone as a fascist:
code
<img aria-roledescription="fascist" src="dt.PNG"
alt="Donald Trump">
This is wrong because you are not identifying the subject of the image as a fascist, you are overwriting the <img> element role so it effectively becomes a <fascist> element. Also, there is no explicit text identification of the subject as a fascist.
A much better way to achieve the aim of identifying a fascist (and not misusing aria-roledescription):
Example of a fascist
code
<figure>
<figcaption>Example of a fascist</figcaption>
<img src="dt.PNG" alt="Donald Trump">
</figure>
