Has someone defined the X protocol in ASN.1?  Does anyone have a
point-of-contact for the OSI group working on integrating X as an OSI
application protocol?  Thanks.

You might be interessted in the following article:

Rita Brennan, Kevin Thompson, Rick Wilder: Mapping the X Window onto
OSI Standards, IEEE Network Magazine, May 1991.

It describes the work of ANSI commitee X3H3.6 and ISO JTC/SC21&SC24
on this. The X Protocol is above ACSE and presentation in this proposal.
It is not ASN.1/BER encoded. They use the normal X bitstream as the
presentation syntax. Nothing prevents you from using other presentation
syntaxes then ASN.1/BER in OSI. That's why there is a presentation
syntax negogiation in the presentation layer.
