That's the general idea, but it's a little narrow. Here are a few
uses of CDATA marked sections, off the top of my head:

- source code
- excerpts from system log files
- user sessions with a shell (like bash or command.com)
- sample XML markup
- ASCII art
- mathematical text and other special notations (such as embedded TeX)

Here's a non-source-code example:

<caution>
<para>If the teletype machine displays the following text, please
leave the building as quickly as possible:</para>
<output><![CDATA
------------------------------------------------------------------------
Earthquake Warning
------------------------------------------------------------------------
]]></output>
</caution>

Good luck with the introduction,

David
