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 <def-list> element should not be used to tag the formal terms and definitions provided in section 3 of many International Standards, or corresponding terms and definitions clauses in other documents. Such terms and definitions sections should be marked up using <term-sec> and the individual definitions should normally be marked up using <tbx:termEntry>.

See the separate documentation for a full description of the use of <tbx:termEntry>.

Model Description

The following, in order:

This element may be contained in:

<ack>, <app>, <app-group>, <bio>, <body>, <boxed-text>, <chem-struct>, <def-list>, <disp-quote>, <fig>, <glossary>, <license-p>, <list-item>, <named-content>, <non-normative-example>, <non-normative-note>, <notes>, <p>, <ref-list>, <sec>, <styled-content>, <supplementary-material>, <table-wrap>, <td>, <term-display>, <term-sec>, <th>


In the following example, the <def-list> element is used to tag a list of symbols with their explanations. This material does not appear in the document's “Terms and definitions” clause; that clause would be tagged with <term-sec> and <tbx:termEntry>, not <def-list>.

      <title>Univariate symbols</title>
      <p>The symbols used when there is only one quality
        characteristic in the class are as follows.</p>
      <def-list list-type="symbol-list">
            <p>factor that relates the maximum sample standard
              deviation (<abbrev>MSSD</abbrev>) to the difference between
              <italic>U</italic> and <italic>L</italic>
              (<xref rid="anx-d">see Annex D</xref>)</p>
