### Why is this important?
Any element that uses an ARIA property must reference a valid `id` attribute.
This enables assistive technologies to precisely identify the referenced element.
<!-- This is where the code snippet is injected -->
<div id="locSnippet"></div>
### What to do
* Update the ARIA property value with the unique `id` value of a valid visible element.
For example:
```
<form action="" method="post">
<label for="ln1">Last Name</label>
<input type="text" name="lastname" id="ln1" value="enter last name" title="enter last name" aria-describedby="ln2">
</form>
<div id="ln2" role="tooltip">Last Name must be alpha only characters</div>
```
</script></mark-down>
<!-- End main panel -->
<!-- This is where the rule id is injected -->
<div id="ruleInfo"></div>
