In particular this paragraph should be updated:
> 
> > Xarray can’t open just any zarr dataset, because xarray requires special metadata (attributes) describing the dataset dimensions and coordinates. At this time, xarray can only open zarr datasets that have been written by xarray. For implementation details, see [Zarr Encoding Specification](https://docs.xarray.dev/en/stable/internals/zarr-encoding-spec.html#zarr-encoding).

Documentation should be in good shape now.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1183534905

- `_ARRAY_DIMENSIONS` is missing
- we are NOT in mode `a` or `r+`. As we don't write NCZarr attributes, this prevents from creating zarr using a mix of NCZarr and Xarray conventions.

I'm not sure what's the best approach with `_NC*` attributes. Currently, after reading the metadata useful to `xarray`, they are hidden or dropped. This is somewhat related to #6448.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1183534905
