`    Quite apart from the grammatical/vocabulary problem (``when vocabulary duty's to be done, to be done``), I think ``Though the governor-general may fulfill many of the roles of a head of state, s/he is not a head of state themselves, but the representative of the head of state`` needs tidying up - for instance, this is not true of Australia. But I don't want to improve the Australian side of things at the expense of accidentally misrepresenting how it is elsewhere. So, before I jump in with both feet, I want to offer other experts the opportunity to get it better expressed than I can myself (``be 'umble, Uriah, be 'umble``). PML.`
