[XeTeX] \usepackage{fontspec} and \bfseries {text}

Okay. If I define

\usepackage{fontspec}
\setmainfont[BoldFont={ScalaSansLF-Regular
Bold},ItalicFont={ScalaSansLF-Regular Italic}]{ScalaSansLF-Regular}

and set

\textbf{bold letters}

the text is not in bold letters, it is set in the mainfont.

If I choose 

\setsansfont{ScalaSansLF-Regular Bold}

the whole text is bold. I.e. the bold font is correctly recognized.

What is to do?

Thank you for your help, Stefan.
