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.

Note: These models represent only the default document types distributed by OASIS.
Actual content models will differ with each new document type.
