I don't understand what you mean.  There's nothing in the definition
of Compound Text that prohibits use private charset definitions in
extended segments that I can see.  (I don't have a recent X Consortium
version, but the R5 version is word for word identical with the
X11R6.4 version that comes with XFree86 4.2, excepting the exception
for using DOCS for UTF-8, of course.  Aargh.  At least they don't
prohibit use of extended segments for UTF-8.)

Are you referring to use of private charsets via the private final
bytes with regular ISO-2022 designations?

Right.  We can't prevent it, but we should document it as
"discouraged" in the strongest possible terms.
