Re: Unsupportable ATK interfaces??

["Padraig O'Briain" <Padraig Obriain Sun COM>]

This suggestion is different from Peter's in a later email which proposes, in 
essence, that the ATK interface should fail silently (and hopefully gracefully) 
if an implementation is not provided.

Marc proposes somthing more ambitious, i.e. that we attempt to tell the caller 
that the interface is not supported. Do we need to do this?
