Attribute can not access a dataset without a parent group

H5fileAttribute requires that a dataset must have a parent group. This is not required by h5py:

import h5py


with h5py.File('/tmp/foo.h5', 'w') as f:
    f.create_dataset('bar', data=1.23)

with h5py.File('/tmp/foo.h5', 'r') as f:
    print(f['bar'][()])

import taurus
myattr = taurus.Attribute('h5file:/tmp/foo.h5::baz')
print(myattr.read().rvalue)

This produces:

1.23
