The related information links of a topic (<related-links>
element) are stored in a special section following the body of the
topic. After a topic is processed into its final output form, the
related links are usually displayed at the end of the topic, although
some Web-based help systems might display them in a separate navigation
Links specified within the <related-links>
element are typically displayed together with links generated based
on a map context; see DITA linking for more information
on map based linking.
Links within a <linklist> element must appear in the order
defined, while those outside of a linklist may be sorted and displayed
in a different order or location (based upon their role, target, importance,
or other qualifiers).
PDF output typically ignores hierarchical links such as those
with roles of ancestor, parent, child, descendant, next, previous,
or sibling, although this behavior is not required.
Note: These models represent only the default document types distributed by OASIS.
Actual content models will differ with each new document type.
Describes the target of a reference. See
The type attribute for detailed information
on supported values and processing implications.
The role attribute defines the
role the target topic plays in relationship with the current topic. For
example, in a parent/child relationship, the role would be "parent"
when the target is the parent of the current topic, and "child" when
the target is the child of the current topic. This structure could be used to
sort and classify links at display time.
