Right. The other alternative would be to provide a custom stage_ref_ex
class implementation that would determine what kind value it is and 
parse/serialize accordingly. Something along these lines:

class stage_ref_ex: public stage_ref_list
{
  ...

  bool special () const;
  void special (bool);  

private:
  bool special_;
};

Then in the parsing constructor you would check whether the element
or attribute text is the special "#all" value. If it is, then you
set the special_ flag. Otherwise, you simply delegate to the
stage_ref_list parsing c-tor. Similar logic will also need to be
implemented in the serialization operator.
