Remarkable, considering they weren't added to XEP-0220 until 2009 and
M-Link was released in 2008 :)

Perhaps you mean the type='error' response to a piggybacking attempt
when you don't implement piggybacking? Since Prosody supports incoming
piggybacking we have never needed this. I was pretty confident that
M-Link is the same here, actually.

I'm asking specifically about the newer type='error' that allows
inclusion of certain errors in lieu of fatal stream errors (
http://xmpp.org/extensions/xep-0220.html#errors ). If M-Link supports
these today, that would be good to know so I can do some interop
