The World Wide Web (WWW) and publishing documents to it and to the Internet has, as we all know, soared to the state of ubiquity. A technology that has made this easier for those who actually engage in this activity is Extensible Markup Language (XML).

XML is a computer authoring language for publishing documents through the WWW onto the Internet, and it provides a significantly greater flexibility and automation potential as compared with the other way of posting to the web, HTML.

Here's a sample of an XML document of an old George Burns and Gracie Alien routine that ended their shows for years. George would say to his wife Gracie as they were signing off,"Say good night Gracie."To which Gracie would reply, and instead of saying "Good night" she assumes the ditz role and says/'Good night, Grade/'which in those days was clever and would get a laugh. We call this document Old joke,'and after the exchange, there is applause from the audience.
