Is it really this:

```python
In [63]: da = xr.DataArray(np.random.rand(3,2), dims=list('ab'), coords={'c':(('a',),list('xyz'))})

In [64]: da.sel(a=(np.isin(da.c, list('xy'))))

array([[0.383989, 0.174317],
       [0.698948, 0.815993]])
Coordinates:
    c        (a) <U1 'x' 'y'

Here's one way:
```python

In [28]: a.where(a.currency=='EUR', drop=True)
Out[28]:
<xarray.DataArray (country: 2)>
array([20., 30.])
Coordinates:
  * country   (country) <U7 'Germany' 'France'
    currency  (country) <U3 'EUR' 'EUR'

I'm not sure whether `.sel` should work for non-`IndexVariables` - thoughts?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,309691307
