Thanks Patrick.

I finished careful reading your clear answers titled with
 "Re: [idn] questions: unassigned code points in nameprep".

What I understand is:

  "saved string" :  generated ACE labels by applications 
                      with known version of nameprep

  "query"        :  received ACE label from other applications
                      the ACE label may have been generated by 
                         unknown version of nameprep

 from this understanding,

 1) I will prefer to use "generated ACE label" and "received ACE label".
 They seem to be  more intuitive.

 2) Current stringprep prohibits old nameprep to encode into ACE labels 
  any unassigned code points. (MUST NOT).

 3) Therefore, Unassigned code points cannot even begin its trip to other applications from the old nameprep applications. 

 4) If we finalize IDN before TAGALOG is added, there is no way to support
  seamlessly support of TAGALOG input in older nameprep applications 
  but for users to upgrade their s/w.
 
 if anyone read and got more  from the answers, add them to this list please.
