One item in a definition (two-part) list.
Related Elements
A <def-list> may take a <label> that provides it with a number, 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.
