<version> Version Statement

A full version statement, which may be only a number, for data or software that is cited or described.


The <version> element is not a generic, all purpose version number; its use is limited to inside the citing elements: <mixed-citation>, <element-citation>, <product>, <related-article>, and <related-object>. See Related Elements below for other version elements and attributes.
The content of <version> may be a simple version number (such as “<version>16</version>” or “<version>XII</version>”). More complex version statements may contain a textual statement (“Fifth PC version, patches 2-3”), dates that the dataset covers, the version number as an ordinal (“3rd” or “3rd version”), or superscripted ordinals (“4<sup>th</sup>” or “10<sup>th</sup> version”).

Best Practice for @designator

Whether the content of <version> is a simple number or a complex phrase, the @designator attribute can be used to hold the simple numerical or alphabetic version number, if there is such a number (<version designator="16.2">16th version, second release</version>).
Related Elements
The other version numbers (besides <version>) that may be recorded in this tag set:
  • For the version of the Tag Set being used in this document, use the @dtd-version attribute on the <article> element.
  • For a version number of the article, use the <article-version> element.
  • For the version of a programming language code fragment, schema, or markup example, use the @code-version attribute on the element <code>. (Note: This is the version of the coded fragment itself.)
  • The version of the language in which a <code> fragment was written is recorded in the @language-version attribute.
