part

The <part> element references a part topic for the book. A new part is started. Use <part> to divide a document's chapters into logical groupings. For example, in a document that contains both guide and reference information, you can define two parts, one containing the guide information and the other containing the reference information.

Example

Part topics that include chapters and subtopics:

<part href="guide.dita">
 <chapter href="intro.dita">
  <topicref href="caring.dita"/>
  <topicref href="feeding.dita"/>
 </chapter>
 <chapter href="setup.dita">
  <topicref href="prereq.dita"/>
  <topicref href="download.dita"/>
 </chapter> 
</part>
<part href="ref.dita">
 <chapter href="commands.dita">
  <topicref href="care.dita"/>
  <topicref href="feed.dita"/>
 </chapter>
 <chapter href="apis.dita">
  <topicref href="acare.dita"/>
  <topicref href="afeed.dita"/>
 </chapter> 
</part>
