Everything that is not visually displayed on the screen is a virtual. Functions, strings, events
listeners, actions, etc. The
h:virtual tag is more than a container for the items.
It is responsible for removing them from the DOM so they are not continually processed by the
browser's parsing engine. This means your pages run faster AND your code is hidden from peeping eyes.
<h:virtual>YOUR VIRTUALS GO IN HERE</virtual>
The next sections will go over how to declare different virtuals within this container.
