hi tom, can you explain what this code aims to do?

for ct in ['creator', 'publisher', 'contributor']:
                iict = getattr(ii, ct)
                if iict:
                    for iict2 in iict:
                        contacts.append(iict2)

code expects ii (identificationInfo) to have a property called 'creator','publ' or 'cont'? this is quite unexpected, when does it happen? it's not in the gmd schema

owslib.iso.MD_DataIdentification and owslib.iso3.MD_DataIdentification have creator, publisher, contributor members (lists) (note that ISO3 additionally includes funder). These are populated on parsing if they exist (as CI_RoleCode values).

In summary, owslib.iso and owslib.iso3 get_all_contacts is convenience function which attempts to capture all contacts in an ISO document.
