JP> I cannot agree more - actually we even have a partial to the problem during the initial design phase and
the WG collectively decided not to mix storing and non-storing in light of the added complexity. I would also
appreciate the feedback of the WG on this, and not add complexity unless this becomes a strong requirement.

Thanks.
