Well, do try again because I'm not understanding your comment at all, but I think it might be important.

The former.

Various informal conventions have been used to introduce formatting line breaks and indents that can be distinguished from those that are actually part of the message.

Can you point to a recent RFC with each of those? My ignorance of SIP is showing here...

Good catch. That's an artifact of the RNG-to-prose converter that Julian slaves over for this document. He has a bit more slaving to do.

Can you tell I changed the name during the writing of the last draft?

I have the same desire, but I haven't found a clean way to do that. We inherit nothing else from the filename, modification date, and so on.
