Given that a few people expressed confusion on that wording, it seems 
necessary. How about:

(iii) A change to the approach in the design team documents (a 
protocol that is independent of Unicode versions, that removes any 
character mapping in the protocol, and has improvements to the bidi 
algorithm).

That does not cover all the changes between IDNA2003 and the design 
team design, (see 
<http://www.ietf.org/internet-drafts/draft-hoffman-idna200x-topics-01.txt>), 
but it covers the high points that could cause a charter refresh.
