Have there been recent changes to ICZN deprecating the concept of
objective synonym? There is an editor on Wikipedia, otherwise
well-respected, who is claiming that names in different genera with the
same epithet (he doesn't say homotypic, but all of his examples are) are
not synonyms. I know this is incorrect for ICBN (and with little effort
I could find chapter and verse), but I don't have enough familiarity
with the current ICZN to either correct myself or counter the argument.
