It's not clear because what does "existing available resources" mean?  
You can read it either way because the new available resource is a  
existing available resource ;-) It needs to-be clarified which  
3921bis does. These type of language issues happen with any  
successful RFC and is why there have been bis releases of SMTP, IMAP,  
POP3, etc...... Implementers will just sort out any fallout from the  
changes or the product will disappear because users will choose the  
working product ;-) I have found after a bis release interoperability  
does improve.
