### Why is this important?
Some HTML elements or attributes have native semantics that map, by default, to implied ARIA semantics.
For predictable interaction and behavior of UI controls, these implicit semantics should only be overridden
as defined in the [conformance requirements for use of ARIA attributes in HTML](https://www.w3.org/TR/html-aria/#docconformance) specification.
<!-- This is where the code snippet is injected -->
<div id="locSnippet"></div>
### What to do
* If a native HTML element fits the intended behavior, use that instead of adding ARIA markup
* **Or**, update the role on the element using the guidance in the [Document conformance requirements for use of "ARIA" attributes in HTML](https://www.w3.org/TR/html-aria/#docconformance) section of the ARIA in HTML specification. This reference provides details of valid ARIA markup on native HTML elements
