specs: clarify SD keyboard focus behaviour
The smart thing would be to have the SD's keyboard focus to be identical to
the MD's keyboard focus (and a BadDevice returned when trying to set an
attached SD's keyboard focus) but alas, the server never implemented this
behaviour and we've now shipped 7 versions with separate SD and MD focus. So
consider this set in stone. oops.
