<navtitle>The navigation title (<navtitle>) element is one of a set of alternate
titles that can be included inside the <titlealts> element. This
navigation title may differ from the first level heading that shows in the main browser
window. Use <navtitle> when the actual title of the topic isn't
appropriate for use in a table of contents, navigation pane, or online content (for
example, because the actual title is too long). Beginning with DITA 1.2, the
<navtitle> element is also available in the
<topicmeta> element in a <topicref> in a map, and
its use is preferred over the <topicref> element's
@navtitle attribute.
