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.
