Parameters ---------- ucd : str The UCD string check_controlled_vocabulary : bool, optional If `True`, then each word in the UCD will be verified against the UCD1+ controlled vocabulary, (as required by the VOTable specification version 1.2), otherwise not. has_colon : bool, optional If `True`, the UCD may contain a colon (as defined in earlier versions of the standard). Returns ------- parts : list The result is a list of tuples of the form: (*namespace*, *word*) If no namespace was explicitly specified, *namespace* will be returned as ``'ivoa'`` (i.e., the default namespace).
