Or, to explain it in more detail: with traditional xmpp you'd have two places in the xmpp stream to do something: 1. after auth and 2. after bind. Because inlining squeezes it all together, these two points in the xmpp stream no longer exist. The two <inline/> elements therefore correspond exactly to this two traditional points in the xmpp stream. XEP-0198 can be enabled after bind and can be used to resume a stream without bind directly after authentication. It can also be used to do only one of these two. That's the reason why it's mentioned in both inline blocks. The occurrence in the SASL2 <inline/> element means "resume" and the occurrence in the bind2 <inline/> means "enable". -tmolitor _______________________________________________ Standards mailing list Info: https://mail.jabber.org/mailman/listinfo/standards Unsubscribe: standards-unsubscr...@xmpp.org _______________________________________________
