Hello Karl
I thought that Martin had presented a use case from CMIP5 which was expected to be repeated in CMIP6
Thus, I thought it likely that specifying data variables related to transects and regions would be done quite widely in CMIP6
You seem to think this is not the case, please may you elaborate a little on why for us?
thank you
mark

Hi Martin, Mark, and all,
I can see that theoretically one might want to define a transect, but do
we have any compelling use case to do this at the moment? I don't think
CMIP6 is such a case.
cheers,
Karl

It think it is sensible to keep it this way and provide a separate mechanism for your transect use case. I think overloading the current bounds mechanism is likely to lead to problems.
