Sectioning Inside Appendices

Question

I am using the following to include appendices at the end of a memoir document:

\documentclass[a4,12pt,oneside,openany]{memoir}
\renewcommand\cftappendixname{\appendixname~}

\begin{document}
\begin{appendices}
\chapter{First Appendix}
\section{Section}
\subsection{Subsection}

\chapter{Second Appendix}
\section{Section}
\subsection{Subsection}
\end{appendices}
\end{document}

I want to include numbered sections and subsections in each appendix, which I can label and cross-reference. When I use \section{sec: Appendix1 Section1}, or \subsection{sec: Appendix1 Subsection1}, only the sections are numbered; the subsection are not, they are merely titled.

Answer 1

You can number subsections by using \setsecnumdepth{subsection} inside the appendices environment:

\documentclass{memoir}
\renewcommand\cftappendixname{\appendixname~}
\begin{document}
\begin{appendices}
\setsecnumdepth{subsection}
\chapter{First Appendix}
First appendix.
\section{A section}
\subsection{A subsection}
\chapter{Second Appendix}
\section{Another section}
\subsection{A subsection}
Second appendix
\end{appendices}
\end{document}
