      <para>DocBook is an example of a document centric DTD that enables you to 
author and store document content in a presentation-neutral form that captures the 
logical structure of the content. The beauty of authoring documents (especially 
technical ones) in a this form is that one can use XSLT to transform a single 
content specification into multiple delivery vehicles such as HTML, PDF, Microsoft 
Help files and Unix man pages. Although we present this recipe in terms of DocBook, 
the techniques are applicable to other public domain document schema or documents 
of your own creation. </para>
