Objects of this class are stored in the TopicMap dictionary. Map items are created automatically at design time and in authoring mode. You can also create them at run time programmatically. Map items created at design time have their ItemType property set to MapItemType.Static, whereas map items created in authoring mode have their ItemType property set to MapItemType.Dynamic. If you create a map item programmatically, you can set this property to any of the two values.
