To save others the lookup, the use case phrasing that Mark signed on to were these words: "In my use case, the whole ensemble is not present, I only have a subset of the members. I have a metadata element telling me how many members there were at the time the ensemble was created, which I would like to encode." The entire thread is titled 'realization | x of n', but it is pretty, umm, rich with detail.
The last email before discussion went silent appears to be mine: > Modified to fit Mark's use case, I think suitable text is: > > name: original_ensemble_size > > description: The number of member realizations in the originally constituted > ensemble.

I will let someone else provide the example of how that is associated with the variable, it will be more authoritative!
