Beginning XHTML

Exstensible HyperText Mark Up Language (XHTML) allows Web developers to design their web pages for use with non-desktop users, such as portable phones, pagers and Portable Digital Assistants. As a hybrid technology, XHTML retains the simplicity of use of HTML, whilst adding some of the extensible functionality of XML. Because of the concise nature of XHTML, it should not require much overhead from the client machine, making it ideal for the time when users can surf the net through their mobile phones.
