用花括号括住一组带有文本的节点

Question

是否可以用花括号将一组节点括起来，并在花括号的右下角附近放置一些文本。

\documentclass[a4paper]{scrartcl}
\usepackage{amsmath,amssymb,amsfonts}
\usepackage{tikz}
\usepackage{tikz-uml}
\usetikzlibrary{shapes.multipart,positioning,fit}
\usepackage{pgf-umlsd}
\usetikzlibrary{arrows}

\begin{document}
\begin{tikzpicture}
    \node[text width=3cm]                       (A)  at (0,0)               {\tiny AAA};
    
    \node[anchor=north west , text width=1cm]   (A1) at (A.south west)      {\tiny BBB};
    \node[anchor=west       , text width=1cm]   (A2) at (A1.east)           {\tiny CCC};
    \node[anchor=west       , text width=1cm]   (A3) at (A2.east)           {\tiny DDD};
    
    \node[anchor=north west , text width=1cm]   (A4) at (A1.south west)     {\tiny EEE};
    \node[anchor=west       , text width=1cm]   (A5) at (A4.east)           {\tiny FFF};
    \node[anchor=west       , text width=1cm]   (A6) at (A5.east)           {\tiny };
    
    \node [inner sep=0pt,
            draw,
            rounded corners,
            fit = (A)(A1)(A2)(A3)(A4)(A5)(A6)
            ] (A13) {}; 
    
    \draw   (A1.north west) -- (A3.north east)
    (A1.south west) -- (A3.south east);    
    
\end{tikzpicture}
\end{document}

    \draw   (A1.north west) -- (A3.north east)
    (A1.south west) -- (A3.south east);    
    
    \draw [red,thick,decorate,decoration={brace,amplitude=5pt,mirror,raise=1ex}]
  (A13.north west) -- (A13.south west) ;
  
    \draw [red,thick,decorate,decoration={brace,amplitude=5pt,raise=1ex}]
  (A13.north east) -- (A13.south east) node[right,xshift=0.5em]{your text};
\end{tikzpicture}
\end{document}

您也可以只使用矩阵，它提供这些花括号作为分隔符，这可能是排列文本“AAA”、“BBB”等的更自然的方式。

\documentclass[tikz,border=3mm]{standalone}
\usetikzlibrary{matrix}
\begin{document}
\begin{tikzpicture}
 \matrix[matrix of nodes,column sep=1.5em,draw,rounded corners=4pt,
    left delimiter=\{,right delimiter=\}](m){
  AAA & & \\
  BBB & CCC & DDD\\
  EEE & FFF & \\
 };
 \path (m-1-1) -- coordinate (aux1) (m-2-1) -- coordinate (aux2) (m-3-1)
  foreach \x in {1,2}{(aux\x-|m.west) edge (aux\x-|m.east)};
\end{tikzpicture}
\end{document}
