使用 xsim 包的简短解决方案列表

当我尝试在包中的环境中使用列表环境（ itemize、enumerate等）时遇到编译错误。shortsolutionxsim

这是一个 MWE。

\documentclass{scrartcl}

\usepackage{xsim}
\usepackage{enumitem}

\xsimsetup{
  exercise/template = default,
  exercise/name = Aufgabe,
  solution/name = Lösung,
}

\DeclareExerciseProperty{shortsolution}

\newcommand*\printshortsolutions{%
  \begin{description}[leftmargin=3cm, style=sameline]
    \ForEachUsedExerciseByType{%
      \def\ExerciseType{##1}%
      \def\ExerciseID{##2}%
      \GetExercisePropertyT{shortsolution}%
        {%
          \item[Kurzlösung ##3] ####1%
        }%
    }%
  \end{description}
}

\NewDocumentEnvironment{shortsolution}{b}
  {\SetExpandedExerciseProperty{shortsolution}{#1}}
  {}

\begin{document}

\begin{exercise}
  This is the exercise
  \begin{shortsolution}
    Some text.
    \begin{enumerate}
        \item 
        Some more text.
    \end{enumerate}
  \end{shortsolution}
\end{exercise}
\begin{solution}
  The Solution
\end{solution}

\printshortsolutions

\printallsolutions

\end{document}

我收到的错误是在 TeXLive-2020 下。

! Use of \\enumerate doesn't match its definition.
\kernel@ifnextchar ...d@d =#1\def \reserved@a {#2}
                                                  \def \reserved@b {#3}\futu...
l.17   \end
           {shortsolution}
If you say, e.g., `\def\a1{...}', then you must always
put `1' after `\a', since control sequence names are
made up of letters only. The macro here has not been
followed by the required stuff, so I'm ignoring it.

! Illegal parameter number in definition of \l__exp_internal_tl.

                   1
l.17   \end
           {shortsolution}
You meant to type ## instead of #, right?
Or maybe a } was forgotten somewhere earlier, and things
are all screwed up? I'm going to assume that you meant ##.

你没有说出你期望的输出，但是

\NewDocumentEnvironment{shortsolution}{b}
  {\SetExpandedExerciseProperty{shortsolution}{#1}}
  {}

记录为将#1（此处的整个环境主体）放入\edef。您不能将带有可选参数的脆弱命令放入 edef 中，否则会出现所示的奇怪内部错误。

如果你使用

\NewDocumentEnvironment{shortsolution}{b}
  {\SetExerciseProperty{shortsolution}{#1}}
  {}

然后它运行没有错误，但我不知道这是否是您需要的输出。
