I am sure your comments still apply, but I'd > like to know which parts are affected. Yes, you're right. I really hate it when people change documents in the middle of reviews.

The problem is that RFC 5296 says to do things that just aren't possible, so we have a situation where we can either continue to create incorrect specifications or correctly specify behavior that contradicts a published RFC. Personally, I'd go for the latter: change the draft to specify what the authors of 5296 obviously _meant_ to say & update 5296 later.
