[XeTeX] problem with small caps

[McCollum, Adam]

Dear list members,

I'm having a problem getting small caps to show up. It works if I don't declare a font (i.e., if I use the default), but I've tried both Linux Libertine and Junicode and the small caps do not show up. Minimal example below. 

Thanks in advance for any tips.

Adam

\documentclass{article}

\usepackage{xltxtra}

\setromanfont[Mapping=tex-text]{Linux Libertine}

\begin{document}

\noindent
Old King \textsc{Cole} was a merry old soul\\
And a merry old soul was he;\\
He called for his \textsc{pipe}, and he called for his \textsc{bowl}\\
And he called for his \textsc{fiddlers} three.

\end{document}
