link

The <link> element defines a relationship to another topic. Links are typically sorted when displayed based on their attributes, which define the type or role of the link's target in relation to the current topic.

The optional container elements for link (<linkpool> and <linklist>) allow authors to define groups with common attributes or to preserve the authored sequence of links on output. Links placed in a <linkpool> may be rearranged or removed for display purposes (combined with other local or map-based links); links in a <linklist> should be displayed in the order they are defined. Refer to those elements for additional explanation.
