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).
