##### SUMMARY
udm_dns_record contains probably copy&paste info from udm_dns_zone module, see https://github.com/ansible/ansible/blob/devel/lib/ansible/modules/cloud/univention/udm_dns_record.py#L64 Thus it's confusing how to use it, if one uses 'udm_dns_zone' in her playbook it would fail because invalid values.
