Version Statement Content: The content of this element 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^th” or “10^th version”). Whether or not the content is more than a simple number, the @designator attribute of this element 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>).

This element is not a generic, all purpose version number; its use is limited to inside citing elements <element-citation>, <mixed-citation>, <product>, <related-article>, and <related-object>.
