In the <vrm> element of a DITA map, use the following attributes:
<metadata>
<prodinfo>
<prodname>Dishwasher</prodname>
<vrmlist>
<vrm release="dishwasher" version="1" modification="2"/>
</vrmlist>
</prodinfo>
</metadata>
During publication processing, Fluid Topics concatenates the vrm version and vrm release into a single custom metadata called version.
This procedure for DITA content also applies to FTML.
