The version can be used to give version information: as of what version an identifier appeared or was deprecated. It should be specified below the element (180) tag, and will be output in the documentation. It can contain the same tags as the descr (172) tag, and is typeset in the same way.
The following is an example:
<element name="myenum"> <descr> The MyEnum type is a simple enumeration type which is not really useful, except for demonstration purposes. </descr> <version>The myenum type appeared in version 2.1</version> </element>
