element(s) to this element.

For example, the following element uses the `"radiogroup"` role. The `"radiogroup"` role requires child elements with `role="radio"` set in a manner that represents the checked or unchecked state of the radio button.

```
<div role="radiogroup">
    <div role="radio" aria-checked="false"></div>
    <div role="radio" aria-checked="true"></div>
</div>
```

Example with an implicit role:

```
<table role= "treegrid">
     <tr>
         <td>
            element with role= "treegrid"
