topic

The <topic> element is the top-level DITA element for a single-subject topic or article. Other top-level DITA elements that are more content-specific are <concept>, <task>, <reference>, and <glossary>.

To support applications that are namespace-aware, DITA DTDs and Schemas provide the following namespaced declarations for topic, and for topic-level elements derived from topic:
ditaarch:DITAArchVersion="1.0" 
xmlns:ditaarch="http://dita.oasis-open.org/architecture/2005/" 
In DTDs, the "ditaarch" prefix is parameterized to enable future specialization.

Example

<topic id="topic">
 <title>Some little topic</title>
 <body>
  <p>Here's a <b><i>cute</i></b>,
  <b>little</b> topic.</p>
  <ul>
   <li>Some item</li>
   <li>Another item</li>
  </ul>
 </body>
</topic>
