About this task
Use this procedure to insert a topichead to a DITA map.
When you add objects to maps or bookmaps, the icons next to some elements have red bar through them. Icons with a red bar indicates that the element is not directly referencing any objects. For example, topichead elements always have a red bar because they contain titles and never reference objects. Conversely, chapters that directly reference a map or topic do not have a red line.
