FW: Terminology, etc.

To the media feature registry working group:

In your opinion, is it appropriate to register "character repertoires" (ability to render a subset
of characters) as media features? 
 
... (from another message in a different forum) ...


 See http://www.isi.edu/in-notes/iana/assignments/media-feature-tags 
Should we use Media Feature (more flexible) or Locale (no delay in registering)? 
I note ISO-639-2 has a language called "mul" (for multilingual), so we could rename character collections as follows (and then register as Media Features at IANA) : 
mul-WORLDA.charcol 
    US-ASCII 
mul-WORLDB.charcol 
    GSM 03.38, or 3G TS 23.038 ??? 
mul-WORLDC.charcol 
    Latin-1 (deprecated) 
mul-WORLDD.charcol 
    minimised MES-1 with Greek 
mul-WORLDE.charcol 
    WGL4 (what Asian characters could be added while keeping font size 
   'manageable' - Hiragana, Katakana??) 
mul-EUROB.charcol 
    MES-2 
mul-EUROC.charcol 
    MES-3 fixed 
jp-JP.charcol 
    something like JIS 208 and some JIS 212...
