Comment: a misconception has been formed (partly my fault) that these elements ''have'' been documented by the IUPAC, when infact they have not.  does ''not'' have an exception for non-documented IUPAC elements. I would also be in favor of creating a list of 'IUPAC placeholder names' if enough references exist. Sorry for the confusion
