DITA maps for context-sensitive help plug-ins contain <resourceid> elements, each of which identifies a concrete help context ID associated with a DITA topic.
    <topicmeta>
        <resourceid id="help_context_ID_string"/>
    </topicmeta>
        
    <topicref navtitle="label attribute in contexts.xml topic element"
        href="path/to/topic.xml">
        <topicmeta>
            <resourceid id="help_context_ID_string"/>
        </topicmeta>
    </topicref>
        
    <topicref navtitle="label attribute in contexts.xml topic element"
        href="path/to/topic.xml">
        <topicmeta>
            <resourceid id="help_context_ID_1"/>
            <resourceid id="help_context_ID_2"/>
            <resourceid id="help_context_ID_3"/>
        </topicmeta>
    </topicref>
        It may be preferable to combine help contexts in the helpKey properties file, instead of defining mapping for multiple help contexts to a single topic in the DITA map. This is a judgment call for the Documentation team responsible for maintaining the DITA map. For more information, see Defining Help Context IDs.
