15. Citations

Citations are fairly simple. Good doc writers use them liberally to avoid plagiarism and give credit where credit is due. Here's an example:

<citation><xref linkend="docbook"></citation>
or
<citation>
   <ulink url="http://www.docbook.org/tdg/html/docbook.html">
   DocBook: The Definitive Guide
   </ulink>
</citation>

And here's what it looks like formatted (Note: I left out the first one because I don't have a cross reference to it in this doc, I'm only showing the second one.)
