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 |
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 |
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 |
collection-type | Collection types describe how links relate to each other. The processing default is "unordered", although no default is specified in the DTD or Schema. unordered Indicates that the order of the child topics is not significant. sequence Indicates that the order of the child topics is significant; output processors will typically link between them in order. choice Indicates that one of the children should be selected. family Represents a tight grouping in which each of the referenced topics not only relates to the current topic but also relate to each other. -dita-use-conref-target See Using the -dita-use-conref-target value for more information. Usage of the collection-type attribute on <reltable> and <relcolspec> is currently undefined and reserved for future use. | (unordered | sequence | choice | family | -dita-use-conref-target) | #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 |
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 |
locktitle | If locktitle is set to "yes", the <navtitle> element or @navtitle attribute is used if it is present. Otherwise, the navtitle is ignored and the navigation title is retrieved from the referenced file. Note: The @navtitle attribute is deprecated in favor of the <navtitle> element. When both a <navtitle> element and a navtitle attribute are specified, the <navtitle> element should be used. yes The navtitle in the map is used. no The navtitle or title of the topic is used. This is the processing default. -dita-use-conref-target See Using the -dita-use-conref-target value for more information. | (yes | no | -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 |
linking | Defines some specific linking characteristics of a topic's current location in the map. If the value is not specified locally, but is specified on an ancestor, the value will cascade from the closest ancestor. targetonly A topic can only be linked to and cannot link to other topics. sourceonly A topic cannot be linked to but can link to other topics. normal A topic can be linked to and can link to other topics. Use this to override the linking value of a parent topic. none A topic cannot be linked to or link to other topics. -dita-use-conref-target See Using the -dita-use-conref-target value for more information. | (targetonly | sourceonly | normal | none | -dita-use-conref-target) | #IMPLIED | No |
toc | Specifies whether a topic appears in the table of contents (TOC). If the value is not specified locally, but is specified on an ancestor, the value will cascade from the closest ancestor. | (yes | no | -dita-use-conref-target) | #IMPLIED | No |
