XML - Enhanced Programming Language

XML (eXtensive markup language) is very similar to HTML regarding the format (tags). The difference is that in XML the programmer can develop their own tags. i.e. 26 to represent things. This is a developing technology and is central to the World Wide Web. External stylesheets can be used to format the web page. This language can be extremley useful for handheld PDA's (Personal digital assistant), which has a web browser within the personal organiser.
