Are homonyms across Codes permitted, for example between plants and animals?

Each of the major nomenclatural Codes (ICBN, ICNB, ICTV) is exclusive; they govern homonymy independently. Thus homonyms (the same name for different taxa) are allowed between Codes. For example, the genus Ficus is available and valid for both a gastropod genus and the plants commonly called figs. It is assumed that points of confusion in referring to organisms in different Kingdoms will be rare, thus homonymy is not controlled in these cases.
