rename netcdf global attribute using xarray in python

Is there a way to rename global attribute names using xarray? The rename command only seems to rename variables and dimensions and not global attributes. I tried this:

with util.open_or_die('AA.nc', perm='r+') as hndl_nc:
    hndl_nc.rename({'src_name': 'dst_name'}, inplace=True)

But I get this error:

AttributeError: NetCDF: Attribute not found

The xarray attrs attribute (which holds the attributes you're accessing) is simply an OrderedDict. There's no method in xarray that explicitly allows this behavior, but the attrs can be modified directly, e.g.:

hndl_nc.attrs['dst_name'] = hndl_nc.attrs.pop('src_name')
