### Why is this important?
For each ARIA attribute (a property or a state) used in an element, a valid value for the attribute must be specified. This enables assistive technologies to present the element appropriately.
<!-- This is where the code snippet is injected -->
<div id="locSnippet"></div>
### What to do
* Provide a valid value for the empty required attribute(s). Refer to the [ARIA practices guide](https://www.w3.org/WAI/ARIA/apg/) for valid values for each attribute.
For example, the following element uses an `aria-live` property. The `aria-live` property requires a valid non-empty value set, one of which is `"polite"`.
```
<div role="range" aria-live="polite">Live region content.</div>
```
