is quite complex. To elaborate, an element component is like a standalone library
that you can call from your page. The name of the component is given by its namespace.

components may have different tags with the same name. Therefore, any reference
to an element component's tag must be prefixed with its namespace. Behaviors were
introduced in IE 5.0 for intrinsic HTML tags. IE 5.5 extends behaviors to custom
tags, which makes element component a more robust feature. Behaviors, in general,
can add properties, methods, and event handlers to tags. Sometimes, you'll see
