Re: WG Review: Domain Keys Identified Mail (dkim)

I believe the text here:


Since experimentation resulted in significant Internet deployment of these
specifications, the DKIM working group will make every reasonable attempt to
keep changes compatible with what is deployed, making incompatible changes only
when they are necessary for the success of the specifications.

implies the need to be clarify the charter in two ways.  The charter needs to 
reaffirm that the IETF has change control over the specifications at this 
point, so that there is no question over who gets to decide whether an 
incompatible change is necessary.  The charter also needs to indicate that the 
working group will consider the relationship of this work to other, existing 
IETF technologies.  That does not imply that it needs to adopt them, but 
explaining why it chose to use, for example, this signature mechanism rather 
than one of the existing ones would help the IETF understand whether this 
mechanism is a better point solution, implies a problem with the existing 
mechanisms which should be fixed in the existing solutions, or should be 
considered as the basis of a more wholesale replacement.   Doing so in its 
first milestone document seems like a reasonable way to accomplish this, but 
doing so in the standards-track specifications also seems reasonable.

                        regards,
                                Ted Hardie
