What happens under the current wording, before the addition above? That is, if 
no AliasMode record was processed, is the addition along the lines of "you can 
only add this if you have it, and if no AliasMode record was processed, you 
don't have it"? Or does the addition solve the problem "if no AliasMode record 
was processed, the thing you append will be harmful"?
