A navigation title is an alternative title for a topic, specified as an attribute on a topicref element.
Navigation titles are usually shorter than the full title, or they could be set, as in the following example, to allow the use of 'scope="peer"' in related links (see Related links).
Example
<concept id="audience">
<title>Audience type</title>
<titlealts><navtitle>Audience</navtitle></titlealts>
<shortdesc/>
<prolog>
