The anchor element provides an integration point that another map can reference in order to insert its navigation into the referenced map's navigation tree. For those familiar with Eclipse help systems, this serves the same purpose as the anchor element in that system. It might not be supported for all output formats.
The mechanism by which map processors discover maps to be anchored is processor specific.
The anchor element is typically used to allow integration of run-time components. For build-time integration, you can use a topicref element to reference another map, or use the conref or conkeyref attribute on an element inside the map.
