Example
This example specifies that myProgram runs on Linux and Windows.
<subjectScheme>
<subjectdef keys="myProgram" navtitle="My Program">
<hasRelated keys="runsOn" navtitle="runs on">
<subjectdef keys="linux" navtitle="Linux"/>
<subjectdef keys="mswin" navtitle="Microsoft Windows"/>
</hasRelated>

</subjectScheme>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 |
| 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.
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 |
| 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 | 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 |
