Attributes

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
processing-role	Describes the processing role of the referenced topic. The processing default is "normal". If the value is not specified locally, but is specified on an ancestor, the value will cascade from the closest ancestor. normal Normal topic that is a readable part of the information. resource-only The topic is used as a resource for processing purposes, but is not a readable unit of information on its own. This topic should not be included in a rendered table of contents, and the topic should not be rendered on its own. -dita-use-conref-target See Using the -dita-use-conref-target value for more information.	(normal \| resource-only \| -dita-use-conref-target)	#IMPLIED	No
scope	The scope attribute identifies the closeness of the relationship between the current document and the target resource. See The scope attribute for more information on values.	(local \| peer \| external \| -dita-use-conref-target)	#IMPLIED	No
format	The format attribute identifies the format of the resource being referenced. See The format attribute for details on supported values.	CDATA	#IMPLIED	No
type	Describes the target of a reference. See The type attribute for detailed information on supported values and processing implications.	CDATA	#IMPLIED	No
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, keyref	Keyref provides a redirectable reference based on a key defined within a map. See The keyref attribute for information on using this attribute. Class and outputclass are described in Other common DITA attributes
