Example 132. Example
The recent versions of a hypothetical product might be logged thus using the vrmlist markup:
<prolog>
<metadata>
<prodinfo>
<prodname>Widge-o-matic</prodname>
<vrmlist>
<vrm version="1" release="2" modification="0"/>
<vrm version="1" release="2" modification="1"/>
</vrmlist>
</prodinfo>
</metadata>
</prolog>
This indicates that the topic covers Version 1, release 2, modification levels 0 and 1 (often expressed as version 1.2.0 and 1.2.1).
