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.

Attributes

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. |
