Hi Oded,

It is not in XKBproto but in XKBlib spec. You can see the only assertion against changing layout on release in general (and the patch in particular) in ftp://ftp.x.org/pub/X11R7.0/doc/PDF/XKBlib.pdf, "Table 16.4 Group Action Types", the last item XkbSA_LockGroup, citing:

"
1. If the XkbSA_GroupAbsolute is set in the flags field, key press events set the locked keyboard group to the group specified by the group_XXX field. Otherwise, key press events add the group specified by the group_XXX field to the locked keyboard group. In either case, the resulting locked and effective keyboard groups are brought back into range depending on the value of the groups_wrap field of the con-trols structure.
2. A key release has no effect.
