Hello Jonathan

I have not adopted the text you proposed straight away. I have included a set of updates in the ticket summary which pick up the uncontentious points, from my point of view.

There are material changes in the text you propose which I want to discuss further and I felt it was easier for me to be able to contrast between the proposal I have raised and your suggested alterations by doing this.

It is not clear to me why the limitation on the use of the axes attribute exists. I don't see what problems occur by having multiple variables with an axis attribute of E. This is metadata about a coordinate (| aux coord | scalar coord), it is an 'Ensemble coordinate'.

With this in mind, I think I do disagree with changing the title of the section to Ensemble Axis. The aim here is to define one or more ensemble coordinate (| aux coord | scalar coord) instances.

thank you for your continued interest mark
