When we deserialize that >structure, it just WILL NOT WORK properly inside of our new Schema object. >So, immediately after deserializing, we need to go through the hash >and change all NOTNULLs to NULLs and so on. > >We know that we need to do that on deserializing because we know that >version 1.00 used NOTNULL.
