On January 22nd, 2008, W3C published the latest working draft for HTML 5.
The HTML 5 working group includes AOL, Apple, Google, IBM, Microsoft, Mozilla, Nokia, Opera, and many hundred other vendors.
Some of the new features in HTML 5 are functions for embedding audio, video, graphics, client-side data storage, and interactive documents. HTML 5 also contains new elements like <nav>, <header>, <footer>, and <figure>.
HTML 5 improves interoperability and reduces development costs by making precise rules on how to handle all HTML elements, and how to recover from errors.
