Summary:  For a while, there has been a struggle for the future of markup on the web, a struggle between the W3C's XHTML 2 and HTML5, developed by the major browser vendors under a separate organizational umbrella. First, the W3C took over HTML5, and now it recently announced the sunset of the XHTML 2 effort. This makes a significant difference to the future of XML on the web, and furthermore, because of HTML5's momentum, it is now a technology that every XML developer already has to deal with. But fans of XML need not despair: HTML5 supports a proper XML serialization. Learn about the XML form of HTML5 including some key differences from older XHTML conventions and learn how to practically apply this vocabulary in modern web browsers.

Summary:  One of the most useful new features in HTML 5 is the standardization of local storage. Finally, Web developers can stop trying to fit all client-side data into 4 KB Cookies. Now you can store large amounts of data on the client with a simple API. This is a perfect mechanism for caching, so you can dramatically improve the speed of your application-a critical factor for mobile Web applications that rely on much slower connections than their desktop brothers. In this second article in this series on HTML 5, you will see how to use local storage, how to debug it, and you will see a variety of ways to use it to improve mobile Web applications.
