Differences between HTML 4.01 and HTML 5
The xmlns attribute in HTML 4.01 is required in XHTML. In fact, it has no effect, but for validation reasons, it is helpful to convert HTML to XHTML. There is no reason to do so in HTML 5, but you can still define the xmlns attribute as "http://www.w3.org/1999/xhtml".
In HTML 5, there is a new attribute: manifest.
