 			<h2>Description</h2>
 			<p>
 				This technique uses the <code>status</code> role from the ARIA specification to notify Assistive Technologies (AT) when content has been updated with information about the user's or application's status. This is done by adding <code>role="status"</code> to the element that contains the <a>status message</a>. The aria live region role of <code>status</code> has an implicit <code>aria-live</code> value of <code>polite</code>, which allows a user to be notified via AT (such as a screen reader) when status messages are added. The role of <code>status</code> also has a default <code>aria-atomic</code> value of <code>true</code>, so that updates to the container marked with a role of <code>status</code> will result in the AT presenting the entire contents of the container to the user, including any author-defined labels (or additional nested elements). Such additional context can be critical where the status message text alone will not provide an equivalent to the visual experience. The content of the aria-live container is automatically read by the AT, without the AT having to focus on the place where the text is displayed. See <a href="https://www.w3.org/TR/wai-aria/#status">WAI-ARIA status (role)</a> for more details.</p>

+<p>Note that since <code>role="status"</code> is currently not treated as atomic by default in some environments, it is advisable to add an explicit <code>aria-atomic="true"</code> if the entire contents of the container should be announced.</p>

 			<h1>Using <code>role=status</code> to Provide Status Message on Shopping Cart</h1>
 			<p>This simple script demonstrates how a shopping cart counter is updated and surfaced using the aria <code>status</code> role. Here the role is placed on the paragraph containing the dynamically updated text, and the shopping cart image's alt provides additional context. Due to the default <code>aria-atomic="true"</code>, a screenreader should announce "Shopping Cart # items" or (depending on browser compatibility) "# items" each time the Buy Pink Flamingos button is selected.</p>
