The ditamap requires specific markup to implement context-sensitive help.
    <topicref navtitle="label attribute in contexts.xml topic element"
        href="path/to/topic.xml">
        <topicmeta>
            <searchtitle>Optional text to override the help About title.</searchtitle>
            <shortdesc>Text for context description.</shortdesc>
            <resourceid id="help_context_ID_string"/>
        </topicmeta>
    </topicref>
    <contexts>
        ...
        <context id="help_context_ID_string"
            title="Optional text to override the help About title.">
            <description>Text for context description.</description>
            <topic label="label attribute in contexts.xml topic element"
                href="PLUGINS_ROOT/doc_plugin_ID/path/to/topic.xml"/>
        </context>
        ...
    </contexts>
           where doc_plugin_ID is the value of the id attribute on the 
           <map> element.
        The following illustration shows how the <searchtitle> and <shortdesc> elements in a DITA map can be transformed into markup in the Eclipse context XML file, and how those items in the context XML file provide the context-specific content rendered in the Help view.
