如何扩展此命令以获取更多参数

Question

我有这个命令（createPerson）已经有9个参数。但是，我需要它采取更多。我已阅读xargs包，但我无法弄清楚如何使用它。您能帮助我将更改应用于方法，或者提出更好的解决方案。我的最低工作代码是这样的：

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{hyperref}
\usepackage{tabularx}           % Til tabeller der tilpaser sig i bredden
\newcolumntype{R}{>{\raggedleft\arraybackslash}r}

\usepackage{xifthen}            % Used to test if an argument is empty
\usepackage{datetime}           % Used to format dates
\newdateformat{timeLineDate}{\THEDAY.~\shortmonthname~\THEYEAR}
\newdateformat{monthYearDate}{\monthname[\THEMONTH]~\THEYEAR}

%Arguments: 
%   1) MANDATORY    - Reference to the current full name
%   2) OPTIONAL     - Full birth name
%   3) MANDATORY    - Called name
%   4) MANDATORY    - Birth date in the format of dd. mmm. yyyy
%       4)              - Day
%       5)              - Month
%       6)              - Year
%   7) OPTIONAL     - Death date in the format of dd. mmm. yyyy
%       7)              - Day
%       8)              - Month
%       9)              - Year
\newcommand{\createPerson}[9]
{
        \begin{tabularx}{\textwidth}{lXRc}%
            Navn:   &   \nameref{#1}  &   \formatdate{#4}{#5}{#6} &   $\star$\\%
            \ifNoArgumentElse{#2}{Kaldenavn:    &   #3}{Fødenavn:   &   #2} &   \ifNoArgumentElse{#7#8#9}{&}{%
                \ifNoArgumentElse{#7}{%
                    \ifNoArgumentElse{#8}{#9}{\monthYearDate\formatdate{1}{#8}{#9}}%
                }{\formatdate{#7}{#8}{#9}} & \cross%
            }%
            \ifNoArgumentElse{#2}{}{\\Kaldenavn: & #3 &&}%
        \end{tabularx}%
}

%Arguments
%   1) The argument to test
%   2) If empty then do this
%   3) If not empty then do this
\newcommand{\ifNoArgumentElse}[3]{
  \ifthenelse{\isempty{#1}}{#2}{#3}%
}

\newcommand{\cross}[1][1pt]{\ooalign{%
  \rule[1ex]{1ex}{#1}\cr% Horizontal bar
  \hss\rule{#1}{.7em}\hss\cr}% Vertical bar
}
