Hi,
I am wondering why the XML schema for PubSub events (
https://xmpp.org/extensions/xep-0060.html#schemas-event) specifies that
the "items" element of events may contain multiple "item" and "retract"
elements:
<xs:element name='items'>
<xs:complexType>
<xs:choice>
<xs:element ref='item' minOccurs='0' maxOccurs='unbounded'/>
<xs:element ref='retract' minOccurs='0' maxOccurs='unbounded'/>
</xs:choice>
<xs:attribute name='node' type='xs:string' use='required'/>
</xs:complexType>
</xs:element>
While
https://xmpp.org/extensions/xep-0060.html#publisher-publish-request
and https://xmpp.org/extensions/xep-0060.html#publisher-delete-request
specify that it is not allowed to publish multiple items,
https://xmpp.org/extensions/xep-0060.html#impl-batch allows that
explicitly.
I could imagine an event containing multiple items triggered after such
a batch processing or if the server caches multiple single item
publications before sending an event notification. But if that should
be possible and handled by clients, where is that specified?
Yes, the confusion is understandable. Working up to version 1.13, batch
processing was first removed [1] and then restored [2], pending
discussion. It seems the restoration was not complete in all places,
including sections 7.1 and 7.2.

It seems to me this is an editorial oversight, and discussion didn't
result in a final removal. It would be good to understand if
implementations currently support batch processing, though.
I know that both Wokkel and Idavoll do support batch processing, but
that's not significant enough to be representative for all implementations.
