For newer xetex the package needs to be updated for the larger range,
the test used in teh latex format

is

\ifdim\the\XeTeXversion\XeTeXrevision\p@>0.99993\p@
  \chardef\e at alloc@intercharclass at top=4095
\else
  \chardef\e at alloc@intercharclass at top=255
\fi



with \e at alloc@intercharclass at top being the maximum value allocated by
\newXeTeXintercharclass
