[XeTeX] Question about polyglossia and babel

[Alexander]

After upgrade to TL 2010 these commands not work. gloss-russian.ldf
now contain code from babel.

minimal example:

\documentclass{article}

\usepackage{polyglossia}
\setmainfont{PT Sans}
\setsansfont{PT Sans Caption}
\setmonofont{DejaVu Sans Mono}
\defaultfontfeatures{Scale=MatchLowercase, Mapping=tex-text}
\setdefaultlanguage[spelling=modern]{russian}
\setotherlanguage{english}

\begin{document}
\title{title}
\maketitle{}
Слово "--- слово.
\end{document}
