I'm intrigued by XML. As I understand it, it is something like a partner to HTML; XML carries (stores and transports) the data, focusing on "what data is", whereas HTML displays the data, focusin on how it looks (http://www.w3schools.com/xml/xml_whatis.asp). "XML is information wrapped in tags" (http://www.w3schools.com/xml/xml_whatis.asp). XML allows for back-adding data (going back and adding new/deleting old information). Since XML stores data in plain text, it makes it possible to merge information from incompatible systems. This, of course, simplifies creating and maintaining information systems, as developers can't predict every element the system will need at the beginning of a project; new needs will develop over time, and will need to be incorporated into the system. XML makes this possible.
