But is it a problem with xltxtra or with the font? I thought you guys  
decided the problem was the font itself.

Well, of course -- Palatino Linotype doesn't offer a feature to access  
lining numbers because they're on by default! That's why the warning  
is being shown. (The font should offer the feature, though.)

I notice that Palatino Linotype also has the bug that the combination  
of lowercase numbers and superscripts doesn't work:

\documentclass{article}
\usepackage{xltxtra}
\setmainfont[Numbers=Lowercase]{Palatino Linotype}
\begin{document}
123 hello\footnote{note}
\addfontfeature{VerticalPosition=Superior}1
\end{document}

I'm only on 0.998.1 at the moment though. Jonathan, this isn't the  
first time I've noticed this so-called "font bug" recently (e.g.,  
where a +lnum or +onum overrides a +sups feature). Is it possible the  
behaviour of the ICU engine has changed in this case? There's no code  
in fontspec to remove font features yet, so this could cause a bit of  
annoyance (to everyone) if large numbers of fonts are affected by this  
problem.
