Hello,
According to
<http://xmpp.org/extensions/xep-0060.html#subscriber-unsubscribe-error-nosub>,
when a user unsubscribes from a non-subscribed node, the server
should return :
<error type='cancel'>
<unexpected-request xmlns='urn:ietf:params:xml:ns:xmpp-stanzas'/>
<not-subscribed xmlns='http://jabber.org/protocol/pubsub#errors'/>
</error>
However according to XEP-0086 an <unexpected-request/> error should
be of type 'wait'.
There's no 1-1 mapping between error conditions and error types -
ยง8.3.3.23 of 3920bis states that unexpected-request SHOULD be wait or
modify, though. I'm not wholly sure that cancel really needs to be a
SHOULD NOT, in effect.
So I'm wondering if this discrepancy is a bug in XEP-0060.
Also, not sure about the real status of XEP-0086. It is supposed to
be deprecated but appears to still be de facto normative.
XEP-0086 explains to server implementors how to represent certain
errors in the older form. It doesn't apply to XEP-0060, since if
clients which predate XMPP are trying to use PubSub services, we're
frankly all doomed.
