Oh, now I understand what you asking. Yes I did suggest that you be
allowed to specify sub-class attributes that don't occur in the
super-class. The syntax would be the obvious - either attrname, or
class.attrname.

As far as syntax is concerned I don't think I'm welded to anything in
particular, so suggestions are welcome.
