On a related point, I'd be keen to open a PR for improved documentation for whatever object `a` is. It seems like the documented Xarray terminology is ""multidimensional coordinate"", right? To me, ""non-index coordinate"" and  ""multidimensional coordinate"" are both pretty vague until you're more familiar with Xarray's way of thinking.

What do you think of the terminology ""alternative"" or ""auxiliary"" dimension? `a` is clearly a dimension in the sense that it has coordinates or labels for all the ""tick marks"" along the `x` dimension. At the very least, I'd love to add a lot more examples of how to actually use these things.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,476103888

In your example, do you consider `a` to be a ""variable""? I thought variables were individual `DataArray` objects ""inside"" `Dataset` objects. My colleagues and I have been referring to objects such as `a` as ""alternative"" or ""auxiliary"" dimensions. Basically, a different labeling of the same coordinates. You also seem to call these [""multidimensional coordinates""](https://xarray.pydata.org/en/stable/examples/multidimensional-coords.html)?

But I do think I see the use case. The point is that you can take an existing dimension's coordinates and set them as the coordinates for an alternative dimension?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,476103888
