Suppressing figure numbers in KOMA-Script captions

Question

I am in the process of replacing the caption package with KOMA-Script in a long document. Where caption allows me to suppress the figure-number at the start of any caption by using \caption*{text}, I see nothing comparable in the KOMA-Script documentation. Can someone enlighten me?

Edit: I would like to suppress the whole "Figure x.y:" marker before the actual caption text, just as caption* does.

As far as I could see in the documentation, there's no build-in equivalent to \caption* in the KOMA classes, but KOMA gives you the tools to easily define such a command:

\documentclass{scrartcl}

\makeatletter
\newcommand\WLcaption[1]{%
  \renewcommand*{\figureformat}{}
  \renewcommand*{\tableformat}{}
  \renewcommand*{\captionformat}{}
  \addtocounter{\@captype}{-1}
  \caption{#1}}
\makeatother

\begin{document}

\begin{figure}
\centering
\rule{3cm}{2cm}
\WLcaption{A test caption without label for a figure}
\end{figure}

\begin{figure}
\centering
\rule{3cm}{2cm}
\caption{A test caption with label for a figure}
\end{figure}

\begin{table}
\centering
\rule{3cm}{2cm}
\WLcaption{A test caption without label for a table}
\end{table}

\begin{table}
\centering
\rule{3cm}{2cm}
\caption{A test caption with label for a table}
\end{table}

\end{document}

Answer 2

Assuming that you mean to use a KOMAScript class by "replacing 'caption' with koma" you could simply redefine \figureformat :

\documentclass{scrbook}

\begin{document}

\renewcommand*{\captionformat}{}   
\renewcommand*{\figureformat}{}

\begin{figure}
\caption{x}
\end{figure}

\end{document}

will strip the whole label.
