XEmacs does not complain about the kbd mapping.

Hmm. No. It maps to 0xfe03 as evidenced by this output of xev, but it is
recognised as ISO_Level3_Shift, which is what I want:

KeyPress event, serial 33, synthetic NO, window 0x3a00001,

    state 0x10, keycode 108 (keysym 0xfe03, ISO_Level3_Shift), same_screen YES,
    XKeysymToKeycode returns keycode: 92
    XLookupString gives 0 bytes: 
    XmbLookupString gives 0 bytes: 
    XFilterEvent returns: False

This is backed up by an extract of my Xorg.0.log:

(**) Option "xkb_options" "lv3:ralt_switch,terminate:ctrl_alt_bksp,compose:menu,lv3:ralt_switch_multikey"

and by:

$ xmodmap -pke | grep 'keycode  92'
keycode  92 = ISO_Level3_Shift NoSymbol ISO_Level3_Shift NoSymbol ISO_Level3_Shift

Running xev and hitting Mod5+w gives:

This is X11R7.4. There are no configuration files any more. The keyboard
layout is built into X now but perfectly correctly set up, with the
exception of the inability to remap Level3 on these 2 keys.
