Sorry,

>If my interpretation is correct, Section 2.2 d should be changed to "The 
order of the fields in a t extension is significant" (a field consists 
from <sep> and subtags represented by 3*8alphanum). 

My suggestion above was wrong - I meant

1) The order of the fields in a t extension is not significant.
2) The order of subtags within a field is significant.

One thing which we may need clarification... 

>Section 2.2 Structure 
> 
>d. The order of the subtags in a t extension is significant (see Section 
2.3 (Canonicalization) Canonicalization). 

I think this line does not match 2.3 Canonicalization - because the 
referenced section says - "with the fields ordered by the separators, 
alphabetically. " 
I think we don't want to make the order of <field> significant - for 
example, assume there is a new <sep> "x0" is introduced - 

und-Cyrl-t-und-latn-m0-ungegn-2007-x0-foo 

and 

und-Cyrl-t-und-latn-x0-foo-m0-ungegn-2007 

would be equivalent (but, the canonical representation is - 
"und-Cyrl-t-und-latn-m0-ungegn-2007-x0-foo" - because field "m0-*" and 
"field "x0-*" are sorted alphabetical order). 

If my interpretation is correct, Section 2.2 d should be changed to "The 
order of the fields in a t extension is significant" (a field consists 
from <sep> and subtags represented by 3*8alphanum). 



Otherwise, the latest edition looks clean and ready to go.
