reference

The <reference> element defines a top-level container for a reference topic. Reference topics document programming constructs or facts about a product. Examples of reference topics include (but are not limited to) product specifications, environmental specifications, equipment lists, parts lists, required tools, language elements, class descriptions, commands, functions, and API information. All of these items provide quick access to facts, but no deeper explanation of related concepts or tasks. Reference topics have the same high-level structure as any other topic type, with a title, short description, and body. Within the body, reference topics are typically organized into one or more sections, property lists, and tables. The reference topic type provides general rules that apply to all kinds of reference information, using elements like <refsyn> for syntax or signatures, and <properties> for lists of properties and values.
