Bernard,

We definitely should try to improve the minutes with the context. But, I
do have to make an observation. We are commonly this poor at being exact
in referencing and being specific when discussing at the mic. Just
something for everyone to think about. That would help and reduce the
risk that a note-taker or chair cleaning up minutes to wrongly attribute
statements to the wrong context.

It would be good if the persons who actually made statements around this
could help clarify what was intended to be referenced.

Thanks

Magnus
