Well, XeTeX 3.1415926-2.2-0.9997.4 doesn't appear to recognize \pdfxform,
unless there's some package that defines this that I'm unaware of.  I just
tried this sample code I had found at
http://newsgroups.derkeiler.com/Archive/Comp/comp.text.tex/2010-04/msg00087.html

% minimal example:
% ----------------------------------------------------------

\documentclass[a4paper]{minimal}

\usepackage[latin1]{inputenc}

\usepackage[T1]{fontenc}

\begin{document}\makeatletter

First example:


\setbox\z@\hbox{Hello world !}

\begingroup

\pdfxform\z@\pdfrefxform\pdflastxform% globally voids \box\z@

\endgroup


\ifvoid\z@

The box is now void !

\else

\copy\z@

\fi


Second example:


\setbox\z@\hbox{Hello world !}

\begingroup

\setbox\z@\hbox{\copy\z@}

\pdfxform\z@\pdfrefxform\pdflastxform% locally voids \box\z@

\endgroup


\ifvoid\z@

The box is now void !

\else

\copy\z@

\fi


\end{document}\endinput


The XeTeX doc I have xetexmain.pdf doesn't mention this either.

Thanks,
