well, you cannot control what's visible in the menu. But you can write a
constraint that checks the selected value. You can make it an
event-driven constraint and assign it to the change attr event. If you
make it priority one then if the user selects the "wrong" value for the
given context she will get a constraint violation and the only choice is
to abort the transaction, so the  attr value will never be set to the
wrong value.
