An alternative approach might be to exploit plain tex to delimit the arguments
in a way that is opaque to LyX. Hence, from the viewpoint of LyX and LaTeX, we
pass a single argument, which then is internally parsed to split it up to
whatever you need. Minimal example (LaTeX):
\documentclass{minimal}
\newcommand*{\epigraph}[1]{%
\def\parsearg##1+##2+{\def\one{##1}\def\two{##2}\relax}
\parsearg#1+
\emph{\one} (\two)
}
\begin{document}
\epigraph{Das Leben ist des Lebens Ziel+unbekannt}
\end{document}
Note that \epigraph gets just one argument, which is then internally split into
two. In the example I have used the plus symbol (+) as delimiter to split the
arguments; the delimiter itself is not printed. However, you might use
whatever you want to delimit the arguments, even complex tokens:
\documentclass{minimal}
\newcommand*{\epigraph}[1]{%
\def\parsearg##1 QUOTE OF ##2\end{\def\one{##1}\def\two{##2}\relax}
\parsearg#1\end
\emph{\one} (\two)
}
\begin{document}
\epigraph{Das Leben ist des Lebens Ziel QUOTE OF unbekannt}
\end{document}
Some additional work is required if you want the second part to be optional,
though this should be possible as well.
