The navigation title (<navtitle>) element is one of a set of alternate titles that can be included inside the <titlealts> element. This navigation title might 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.
