The PEX Protocol specification is part of the R4 distribution. Not the
source. See X11R4/mit/doc/extensions/PEX/*

You can get a copy of the source by waiting about 1 year. There is a PEX
consortium that is funding a sample implementation. That sample
implementation will be released to MIT at the end of this year, 1990. At
some point after that it will become part of the X distribution. The
sample implementation is not too far off schedule and will be available
to X consortium members as part of alpha and beta programs this summer
and next fall.

Of course, if you are writing applications then you should be adapting
to the PHIGS application program interface (API). That is what PEX will
export as the interface.
