ok understood - so it basically aligned with the idea i had,
and the separate msg vs. extending the answer message sounds
more like an implementation/backward compatibility detail than
a major architectural difference.

thanks a lot for taking the time to reply - even if it is a repetition
of something already discussed, it is not wasted effort
as not everybody is aware of previous discussions.
