[XeTeX] selecting lucida sans oblique

[Sébastien Mengin]

Dear xelatex users,

Do you observe the same behaviour as I do with the following code:

\documentclass{book}
\RequirePackage{fontspec}
\RequirePackage{xunicode}
\RequirePackage[french]{babel}
\setmonofont{Lucida Sans Typewriter}

\begin{document}
\texttt{\emph{test}}

{\bfseries\texttt{\emph{test}}}

\end{document}

Here, both «test» are typeset BoldOblique.
What do I have to do to select italic with this font?

Thanks in advance,
S.
