Assuming you know that it's the last one (while building the object), one approach could be:

    * LIST {'createdefault': True} +numbers:
        P BOOL { 'default': false } last_number
        * CSVINT +numbertype
        if self.last_number:
           * CSVSTRING {'quotechar': None, 'default': "", 'terminator': None } +number
        if not self.last_number:
           * CSVSTRING {'quotechar': None, 'default': ""} +number
