The arrival of support for XML - the Extensible Markup Language - in browsers and authoring tools has followed a

wondering, "What can XML and its associated standards really do for me?" Getting the most from XML requires
being able to tag and transform XML documents so they can be processed by web browsers, databases, mobile
phones, printers, XML processors, voice response systems, and LDAP directories, just to name a few targets.
