Figures, ALT text and lightboxes

Hello all,

We're using FIGURE with FIGCAPTION to provide an image and a description of the image + photographer credit.

WebAIM's excellent article Alternative Text suggests that no ALT is necessary, the FIGCAPTION does the work.

But we show ALT="" in the IMG tag.

The same article also says that an image with an anchor must never have a missing or null ALT attribute.

We don't use the ANCHOR element but we do use a DATA-URL attribute in the FIGURE tag.

My question: is this good?

<figure data-url="URL">
<p><img src="IMAGE_URL" alt="" /></p>
<figcaption>
<p>CAPTION</p>
</figcaption>
</figure>

Thanks for your consideration.
