What About XML?
So what do SGML and the Internet revolution have to do with XML? Let me tell you a secret: XML is just SGML wearing a funny hat; XML is SGML with a sexy name. In other words, XML is an evolution of SGML. The problem with SGML is that it takes an information management professional to understand it. XML represents an attempt to simplify SGML to a level where it can be used widely. The result is a simplified version of SGML that contains all the pieces of SGML that people were using anyway. Therefore, XML can help anyone future-proof content against future uses, whatever those might be.
That's power, baby!
