Beyond Text and Graphics: XML Makes Web Pages Function Like Applications 

XML is displacing the traditional 'web page'--generally a static document, created with HTML. Most traditional web pages offer only slim interactivity and rely on an overworked server and CGI script. XML is promoting the concept of a 'weblication' (web application) that can work wonders on the web client without generating so much Internet traffic.
