For some reason, the spaces breaks parsing of the range option, this
example works for me (but I only run it with luatex, xetex don't see my
texlive fonts and I'm lazy to configure it):
\documentclass{article}
\usepackage{amsmath}
\usepackage{unicode-math}
\setmainfont{Linux Libertine O}
\setmathfont{xits-math.otf}
\setmathfont[range=\mathit/{latin,Latin,greek,Greek}]{Linux Libertine O Italic}
\begin{document}
Transfinite induction will reveal that $\kappa$ is $\alpha$-Mahlo for each
$\alpha < \kappa$. We have proved elsewhere that $\kappa$ is 1-Mahlo, and
hence 0-Mahlo. If $\kappa$ is $\alpha$-Mahlo for all $\alpha$ below some
limit ordinal $\lambda < \kappa$, then $\kappa$ is $\lambda$-Mahlo by
definition.
\end{document}
Besides removing the spacing, you should be using "Linux Libertine O
Italic" unless you want upright math of course. Apart from that, you
should be using \usepackage not \RequirePackage (the later is supposed
to be used in styles and classes AFAIK).

Right, and this warning should be harmful as regard of this context (it
basically means you want get proper radicals or large operators and
stuff like that, but you are using XITS Math for that anyway).

Their example does not have spaces, so I'm not sure of this is a new
regression or it was like that from the start.

Hope this helps.
