 I'm not sure I get what you mean. Currently there's kxkb (which is actually 
more binaries because of kdeinit etc. but that's irrelevant) and there's 
kcm_keyboard(?) which is for configuring. My idea is that kxkb's 
functionality would be limited to just to displaying the indicator and doing 
the actual keymap switch, there would be no dependency on libxklavier as 
that's not necessary for this. All the remaining functionality like 
configuring, preparing keymaps for kxkb would be done in kcm_keyboard (or 
wherever you want actually), kxkb would only do some check that the prepared 
keymaps are ok and if not it'd run this second tool to generate them. The 
basic idea is that kxkb is as simple as possible and without dependencies on 
things like libxklavier/libxml2, the rest are details :).
