MWE:

\documentclass{acmart}
\begin{document}

\begin{figure}[h]
  \caption{Lorem}
  \Description{ipsum}
\end{figure}

\end{document}

LaTeXML output:

    <toccaption><tag close=" ">1</tag>Lorem</toccaption>
    <caption><tag close=". ">Figure 1</tag>Lorem</caption>
    <ERROR class="undefined">\Description</ERROR>
    <p>ipsum</p>
