Comments on draft-hoffman-imaa-03

Paul,
all,

a few comments on the document follow:

Section 2: "To allow [...], IDNA uses an 'ACE local part'". You mean "IMAA 
uses", don't you?
Section 2: "ACE infix". Maybe adding a few words there on its role in 
IMAA?
Section 4: "If a local part is represented using a character set other 
than Unicode or US-ASCII, it will first need to be transcoded to 
Unicode.". I don't understand this requirement on the character set used 
to the input and I think it is not relevant here. Nevermind if I use 
UTF-8, or UTF-16 or Latin-1. If my local encoding is, for instance, 
Latin-9 and I have an implementation of ToASCII running in my system that 
deals with my local encoding, the operation will succeed. Relevant is that 
my system correctly interprets the character encoding when reading from an 
input stream (socket, file).
Section 4.1, step 5.d: Could we add some wording on the magic of 59? At 
the first reading, I didn't know what was the point of this test.

Best regards,
Marcos Sanz
