[boost] [parameter] Extendable named parameter keywords

Hi,

I'm creating a GUI library (still in pre-alpha) using the named
parameter library for the create function.
It has a interface like this:

wnd_lock<frame_window> w = create<frame_window>( _driver = gtk
  , _pos = std::make_pair(20, 20), _size = std::make_pair(600, 400) );

Until here everything is alright.
But, for some controls, we must have extended keywords:

wnd_lock<text_box> text = create<text_box>( _parent = w, _pos =
std::make_pair(0, 0)
  , text_box::_multi_line = true );

Is it achievable?

Thanks in advance,
