Everything can be done this way :) If attached diff is acceptable I can
replyof is something like field with type of reply of some request,
instead of some structure. Don't you think that these fields could be
also replaced by fields of referenced structure ?
Referencing replies of requests can be done another way, by explicitly
naming replies ( I think that change would require change in all xml's,
not to mention ensuring backwards compatibility ).

Right, every time the syntax changes, every generator should be updated,
but it doesn't mean that syntax can't change. XKB needs syntax changes (
at least conditional tags ), so why not think about what tags/changes
are needed and feasible now ?
