Section whose content is typically a list of terms and definitions, usually tagged as one or more two-part lists called <def-list>. Typically part of the back matter of a document.
The <glossary> 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>.
The following, in order:
