  - <p>Hi, I'm the <em>first XSP page ever</em>.</p>
  - 
  - <p>This page is an example of usage for XSP technology which is being 
  -    designed to add dynamic XML capabilities to the Cocoon publishing 
  -    framework.</p>
  -    
  - <p>In this page, the content is automatically generated by translating this
  -    template page into some source code (Java in this case) and then executed
  -    at request time (as servlet). The separation between content and logic
  -    is done using the transformation capabilities of XSL, tranforming the
  -    template elements used to create this page into XSP elements which 
  -    discriminate the content from the logic and are correctly interpretable
  -    from an XSP engine.</p>
