[XeTeX] mathspec and MnSymbol

This was exactly what I expected to use xetex in scientific projects!

Thanks, now I will use the compact version (MnSymbol as an option of mathspec).

I will not say that I really need all these fonts, but I thought there was no limitation.

Here is a very simple example with which I make experiments (the choice of the fonts is not yet definitive for a project!):
-----------------------
%!TEX TS-program = xelatex
%!TEX encoding = UTF-8 Unicode
\documentclass[12pt,a4paper]{article}
%\usepackage{MnSymbol}
%\usepackage{mathspec}
\usepackage[MnSymbol]{mathspec}

\setromanfont[Mapping=tex-text,Scale=1.]{Minion Pro}
\setsansfont[Mapping=tex-text,
{Cronos Pro}
\setmathsfont(Digits,Latin,Greek){Minion Pro}
\setmathrm{Lucida Bright}
\setmathsf{Lucida Sans Regular}
\setmathtt{Lucida Sans Typewriter}
\setmathcal{Lucida Calligraphy Italic}
\setmathbb{Moonglow}
%\setmathfrak{Lucida Blackletter} % doesn't work, so commented


\begin{document}
Some text

$E=mc^2$

$\mathrm{ABCDEabcde}$

$\mathsf{ABCDEabcde}$

$\mathtt{ABCDEabcde}$

$\mathcal{ABCDEabcde}$

$\mathbb{ABCDEabcde}$

$\mathfrak{ABCDEabcde}$

\end{document}
------------------------

I get the message:
-----------------------

?

-----------------------

If I comment out 
\setmathsfont(Digits,Latin,Greek){Minion Pro}
then there is no more these messages (and the font for $E=mc^2$ is the usual one in tex)

It looks like there are indeed too much fonts in the game!

I will make other experiments to get something working!

Thanks a lot
