This is now fixed in `ucharclasses.sty'.  However, there's still a
limitation in `latex.ltx'.  The code

  \ifx\XeTeXcharclass\@undefined
  \else
  \def\newXeTeXintercharclass{%
   \e at alloc\XeTeXcharclass\chardef\xe at alloc@intercharclass\m at ne\@cclv}
  \fi
  \ifx\XeTeXcharclass\@undefined
  \else
    \countdef\xe at alloc@intercharclass=257
    \xe at alloc@intercharclass=\z@
  \fi

is not correct for XeTeX 0.99994 and newer since up to 4096
\XeTeXcharclass registers are now supported.  Is there a chance that
`latex.ltx' gets updated accordingly before TeXLive 2016 is out?
