XEP-0060 states at
"If configured to do so, the service can include the publisher of the item"
as in "<item ... publisher='some_jid'>" but nothing more about this
throughout the document.
I assume it's meant as a per service configuration, so either all or no
node would include the publisher. And I wondered if it wouldn't make sense
to have that (also?) as a per node configuration option. If so, what
would/could it look like?
<field var='pubsub#item_publisher' type='boolean'
label='Whether to include the publisher\'s jid with event
I'd volunteer to add it to the XEP if people see fit.
