AttributeError: 'NoneType' object has no attribute 'replace'

Getting the following when requesting a DOI ref.

The ref is DOI.10.6028/NIST.SP.800-53r5.

Calling as follows:

from doi2ietf import process_doi_list
doi_list = process_doi_list(['DOI.10.6028/NIST.SP.800-53r5'], 'XML')

Getting error:

Actually, the error happens only if XML is requested. DICT is returned without an error.

(And the DOI apparently exists, it’s the same as in #11)
