Thanks James.

Which registry are you referring to for script and language tags?
Is this in the context of glyphs or do you just mean the IANA language
tag registry?

Given the (un)workable approach, do you then intend to have variants of
code2000 for CJKT, so one can make the appropriate assignments? (ugh!)

Also, this approach means I have to ask each Unicode font vendor, "Which
language is your multilingual font designed for?"
so I know which CJKT assignment is appropriate for that font...

(I hope this doesn't read like I am attacking you, I am not. I am just
trying to highlight the difficulty I am having with this.)
