BTW, I checked over 1.1rc5 and found a few typos and infelicities, so
I've checked 1.1rc6 into git:
http://xmpp.org/extensions/diff/api/xep/0178/diff/1.1rc5/vs/1.1rc6
That obviously does not document what is currently happening "on the
wire"...
Do we need a note stating that the authorization id in the current version
contains a spurious newline?

I have not seen this in any implementation, so maybe developers are smart
enough to do the right thing.
