<h2>Definition and Usage</h2>
<p>The Form control defines a container for mobile controls.</p>
<p>Each mobile page must have at least one Form control, and each Form control
can have a number of mobile controls.</p>
<p>Note that mobile pages can have multiple Form controls. This is due to the
nature of mobile devices. Mobile devices have small screens and it is very
normal to navigate between screens with simple links.</p>
