Example
A region declared as a web application, as opposed to a web document. In this example, the application is a simple calculator that might add two numbers together.
<div role="application">
<h1>Calculator</h1>
<input id="num1" type="text"> + <input id="num2" type="text"> =
<span id="result"></span>
</div>
