ah, I don't think I'd noticed xetex was using _quite_ so many digits
in its version number:-)
as you say the test is a bit suspect but it works in the one case it
needs to work so D guess it's OK!

hi David,

I don't know the details here but
as

*\message{\number\dimexpr0.1pt}
65530
*\message{\number\dimexpr0.2pt}
65531
*\message{\number\dimexpr0.3pt}
65531
*\message{\number\dimexpr0.4pt}
65532
*\message{\number\dimexpr0.5pt}
65533
*\message{\number\dimexpr0.6pt}
65533
*\message{\number\dimexpr0.7pt}
65534
*\message{\number\dimexpr0.8pt}
65535
*\message{\number\dimexpr0.9pt}
65535

it looks a bit of luck that it jumps at 0.4.

Just in case people need to distinguish 0.8 from 0.9
or 0.5 from 0.6 if that is actually relevant
to XeTeX and want to copy this method ;-)

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@>0.3\p@
  \chardef\e@alloc@intercharclass@top=4095
\else
  \chardef\e@alloc@intercharclass@top=255
\fi



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