<navref>
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.
            
Note that not all output formats support such linking. In order to include another
               map directly
               without depending on the output format, use a <topicref> element with the
               @format attribute set to "ditamap". The effect is similar to using a
               @conref attribute. For example, the following markup represents a literal
               inclusion of the map
               other.ditamap:
<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.
