Creating Documents with Structural Markup  

Now we come to the point of actually producing documents using structural markup—either eXtensible Markup Language (XML) or Standard Generalized Markup Language (SGML). Our sequence of topics illustrates the recommended steps to follow when you first implement structural markup: Learn about it and convince yourself and your organization of its benefits, identify your specific goals and expectations, and spend plenty of time selecting or designing your document structures. Only then should you get down to the specifics of how to produce XML or SGML documents. If you simply try to drop in an XML editor to replace your current word processing application, you will be lucky to avoid total disaster.
