[idn] Nameprep & Uniprep



The Uniprep issue Paul brought up during the wg meeting I think is very interesting and personally, I have thought that there should be something like this all along.  Anyway, these are my thoughts:
 
Uniprep - Unicode Identifier Preparations
Nameprep - Domain Name Preparations
 
Uniprep will be a looser specification for general Unicode Identifiers.
 
Nameprep will be include mandatory compliance with Uniprep and then on top of it will include some or all of the following:
- additional mandatory preparations specifically for domain names (might not be required)
- Optional elements for zone operators
    - TS Conversion
    - Jpchar
    - Hangulchar
    - others...
 
In other words, most of the existing Nameprep might be moved to Uniprep, while Nameprep becomes an architectural document for prepping domain names which references to Uniprep and the other language specific mappings, plus possibly some additional preparations specifically for domain names.
 
Does this make sense?

PS. perhaps Uniprep might better be discussed outside of the IDN wg...?...
