Hi @sfinkens. Thank you for raising an issue.

I think what you actually want would be ```python In [16]: ds = xr.Dataset({'data': ('x', [1, 2]), ...: 'x': ('x', [1, 2]) ...: }, coords={'x_bnds': (('x', 'bnds'), [[0.5, 1.5], [1.5, ...: 2.5]])}) ...: ds['x'].attrs['bounds'] = 'x_bnds' ...: ds = ds.expand_dims({'time': [0]})

In [17]: ds
Out[17]: <xarray.Dataset> Dimensions: (bnds: 2, time: 1, x: 2) Coordinates: * time (time) int64 0 * x (x) int64 1 2 x_bnds (x, bnds) float64 0.5 1.5 1.5 2.5 Dimensions without coordinates: bnds Data variables: data (time, x) int64 1 2 `` wherex_bnds` would be a coordinate rather than a data variable.
