DITA maps for context-sensitive help plug-ins must contain a <topicmeta> element as the first child of the <map> element, and for each UI plug-in whose help context IDs are identified in the map, that <topicmeta> element must contain one <othermeta> element that identifies the UI plug-in.
<map id="org.eclipse.datatools.ui.doc"> <topicmeta> ... <othermeta name="ui-plugin" content="org.eclipse.datatools.connectivity.ui"/> <othermeta name="ui-plugin" content="org.eclipse.datatools.connectivity.ui.dse"/> </topicmeta> ... </map>
The name attribute value "ui-plugin" is a fixed, literal string. The content attribute value is the Eclipse plug-in ID of a UI plug-in.
Nested maps that contribute context-related help topics must include the same markup to identify each UI plug-in whose context IDs are identified in that map.
