Extension points
The DITA Open Toolkit provides a series of extension points that can be used to integrate changes into the
core code. Extension points are defined in the plugin.xml file for each plug-in. When plug-ins
are installed, the DITA-OT makes each extension visible to the rest of the toolkit.
