I don't think you should use nillible for the case of someone who has no middle name. That is simple optionality.

nillible is for a more esoteric purpose: where whether that person has a middle name or not has not been disclosed. This may because you don't know, the client didn't ask, or you dont want to tell. 

I think there's also the use case where a middle name was present (erroneously?) and has been removed, perhaps leaving a modification time stamp attribute.

Pretty horrible way to do it, IMO, but there you go

Thanks,
