The navref element represents a pointer to another map which is preserved as a transcluding link in the result deliverable rather than resolved when the deliverable is produced. Output formats that support such linking can integrate the referenced resource when displaying the referencing map to an end user.
For example, if a map is converted to the Eclipse help system format, the DITA element <navref mapref="other.ditamap"/> is converted to the Eclipse element <link toc="other.xml"/>. When Eclipse loads the referencing map, it will replace this link element with the contents of the file other.xml, provided that the file other.xml is available.
<topicref href="other.ditamap" format="ditamap"/>

Inheritance
- map/navref
Example
In this example, the map titled "MyComponent tasks" references the maps othermap2.ditamap and othermap3.ditamap.
<map title="MyComponent tasks"> <navref mapref="../com.ibm.xml.doc/othermap1.ditamap"/> <navref mapref="../com.ibm.xml.doc/othermap2.ditamap"/> </map>
Attributes
The following attributes are available on this element: Universal attribute group, outputclass, keyref, and the attribute defined below.
- mapref
- Specifies the URI of the map file or non-DITA resource to be referenced. It might reference a DITA map or a resource that is appropriate for your output format (such as XML TOC file for Eclipse output).
- keyref (DEPRECATED)
- The keyref attribute was unintentionally defined for navref in the original DITA grammar files. It is retained for backwards compatibility. The attribute will be removed in a future release, and processors are not expected to support it.
