<def-list> Definition List

List in which each item consists of two parts: 1) a word, phrase, term, graphic, chemical structure, or equation, that is paired with 2) one or more descriptions, discussions, explanations, or definitions of it.


The definition <def> part of an item in a two-part (definition) list need not be a “definition” in the strict dictionary sense of that word. Such a definition could be a discussion, explanation, expansion, or something that tells the reader about the <term>. When a <def-list> is within a <glossary> element, the definitions are assumed to be real definitions.
Related Elements
A <def-list> may take a <label> that provides it with a number or other designator, followed by an optional <title> naming the entire list, followed by optional headings for terms and their definitions. <term-head> contains the heading over the first (term) column, and <def-head> contains the heading for the second (definition) column; neither serves as a container element for terms or definitions. Individual <term>s and their <def>s are paired in <def-item>s. Definition lists are recursive, so following all the terms and definitions, there may be one or more embedded <def-list> elements.
