###### Inheritance

- topic/vrm

###### 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).
