The <mapref> element is a convenience element that is equivalent to a <topicref> element with the format attribute set to "ditamap". The hierarchy of the referenced map is merged into the container map at the position of the reference, and the relationship tables of the child map are added to the parent map.

| Name | Description | Data Type | Default Value | Required? |
|---|---|---|---|---|
| navtitle | Specifies the title of the topic as it will appear in the navigation or tables of contents that are generated from the map. Beginning with DITA 1.2, the preferred way to specify the navigation title in a map is with the navtitle element, available inside the topicmeta element. | CDATA | #IMPLIED | No |
| href | A pointer to the resource represented by the <topicref>. See The href attribute for detailed information on supported values and processing implications. References to DITA content cannot be below the topic level: that is, you cannot reference individual elements inside a topic. References to content other than DITA topics should use the format attribute to identify the kind of resource being referenced. | CDATA | #IMPLIED | No |
| keys | Introduces one or more global identifiers for a resource referenced from a map. See The keys attribute for details on how to use the keys attribute. | NMTOKEN | #IMPLIED | No |
| keyref | Keyref provides a redirectable reference based on a key defined within a map. See The keyref attribute for information on using this attribute. | CDATA | #IMPLIED | No |
| query | This attribute is deprecated. It may be removed in the future. | CDATA | #IMPLIED | No |
| copy-to | Use the copy-to attribute on the
<topicref> element to provide a different file name
for a particular instance of the topic in the map (for example, to separate out
the different versions of the topic, rather than combining them on output). The
links and navigation associated with that instance will point to a copy of the
topic with the file name you specified.
Use the <linktext> and <shortdesc> in the <topicref>'s <topicmeta> to provide a unique name and short description for the new copy. |
CDATA | #IMPLIED | No |
| format | The format attribute identifies the format of the resource being referenced. For elements like this one that are designed to reference another map, the value defaults to "ditamap". See The format attribute for details on other supported values. | CDATA | ditamap | No |
| topicref-atts-without-format attribute group (collection-type, processing-role, type, scope, locktitle, linking, toc, print, search, chunk) | A related set of attributes. See topicref-atts, topicref-atts-no-toc, and topicref-atts-without-format attribute groups. | |||
| univ-atts attribute group (includes select-atts, id-atts, and localization-atts groups) | A set of related attributes, described in univ-atts attribute group | |||
| global-atts attribute group (xtrf, xtrc) | A set of related attributes, described in global-atts attribute group | |||
| class, outputclass | Common attributes described in Other common DITA attributes |
