[XeTeX] Slanted Latin Modern specification with fontspec

[Sebastián González]

Hi,

I am new to Xe(La)TeX and fontspec. After searching the mailing list  
archives and elsewhere, I haven't figured out a way to specify slanted  
fonts in fontspec. Commands such as \textrm, \textsf and \texttt work  
fine, thanks to the following commands. But how can I specify "Latin  
Modern Roman Slanted" so that \textsl works as well?

\setromanfont[SmallCapsFont={Latin Modern Roman Caps}]{Latin Modern  
Roman}
\setsansfont{Latin Modern Sans}
\setmonofont[SmallCapsFont={Latin Modern Mono Caps}]{Latin Modern Mono}

I am using an unmodified TeX Live 2007 distribution (MacTeX-2007).

Thanks in advance !
