Part of the disco#info xmlns for muc rooms (XEP-0045) allows for additional information discovery besides just "features" and "identities". These are specified by the jabber:x:data xmlns. http://www.xmpp.org/extensions/xep-0045.html#disco-rooms Example 8 I've attached a trial fix that works for muc rooms. It will probably have to be tested more thoroughly in other disco#info situations besides muc. The included zip contains a diff file and my version of InfoDiscoExtension.as.
