Manual:Html.php

Html.php contains the Html class. This class is a collection of static functions that serve two purposes:
 * 1) Implement any algorithms specified by HTML5, or other HTML specifications, in a convenient and self-contained way.
 * 2) Allow HTML elements to be conveniently and safely generated, like the current Xml class but a) less confused (Xml supports HTML-specific things, but only sometimes!) and b) not necessarily confined to XML-compatible output.

rawElement
Returns an HTML element in a string.
