| This can be used to modify either the name or additional data for any items 
that are already in your server-stored information. It is most commonly used

ID# from the type 0x00c9 TLV in the additional data of the parent group, and 
then send this SNAC containing the modified data. Server should reply via 
SNAC(13,0E).
