Hey there, when implementing parts of XEP-0060 I came across a maybe inconsistency when it's about unsubscribing from a Node (Section 6.2.2 - http://xmpp.org/extensions/xep-0060.html#subscriber-unsubscribe).
If we'd allow to also have a the resulting subscription element in the response, the implementation can be kept more generic, you always reply with the resulting status of the subscription, no matter if it was a subscribe or an unsubscribe. Thus my PR at https://github.com/xsf/xeps/pull/106 I am aware that for unsubscribing the additional information given is redundant. That's why I changed it to MAY after I first suggested a SHOULD there. Regards, Stefan
