However it looks like no xarray code contains the transform keyword. However I definitely can use it in calls to plot(). I don't understand what is going on. Can someone enlighten me?

Yes, this is what I meant with xarray not being directly "cartopy aware". The reason is that xarray intends to be a general library, and tries to avoid defining too many keyword arguments in order to avoid confusion. However, xarray passes along any kw argument you want to the underlying mpl plot function (https://github.com/pydata/xarray/blob/master/xarray/plot/plot.py#L379). You'll have to catch it first, either from the kwargs dict or by adding your own to the signature (the latter being recommended only if necessary, for the reason I mentioned above)
