I am not sure that it is that simple, but anyhow.

Well as far as I can remember I tried that out, and it never worked out
for Xemacs, at some point its autor told me he would come back, in any
case that is not a real problem, it is just a case where some
functionality is not working.

All I am asking you, it not to remove XEmacs compatibility. It would be
a nightmare that one day I try to open a latex file with the latest
auctex version and I obtain an error message because some functions are
not defined. Couldn't you just do the following:

    -  all new features you add in are GNU Emacs tested only so they
       might work under XEmacs or not (and if some XEmacs hacker wants
       to implement it great).

    -  but still even a "crippled" version would work under XEmacs?
