### Why is this important?
An HTML `<article>` element, or any element with an explicit `"article"` role is a type of ARIA landmark region.
When there are multiple article regions, they must have unique labels, so people who use assistive technologies can quickly identify and navigate to each `"article"` region.
<!-- This is where the code snippet is injected -->
<div id="locSnippet"></div>
### What to do
* For each `<article>` element or element with `role="article"`, either set the value of the `aria-labelledby` attribute of each article to the `id` value of any visible text that appropriately and uniquely describes that article's purpose;
* **Or**, use the `aria-label` attribute to add an invisible, unique, non-empty label to each element with the `"article"` role.
For example:
```
<article aria-label="weather portlet">
...
</article>
<div role="article" aria-labelledby="t1">
<h1 id="t1">Stock Ticker Portlet</h1">
...
</div>
```
