You're misunderstanding me.
If a client sends an explicit subscription to a node on a pubsub
service held on a foreign domain whose jid happens to be a bare
jid, then notifications will be filtered by the client's local
server, effectively breaking the subscription.
Indeed, and I still don't understand what you are talking about.
Okay, bear with me, and I'll try to explain.
The automatic subscription on a PEP service is the only one that
should be filtered.
For instance:
"A PEP service MUST support the "filtered-notifications" feature
defined in Section 9.2 of XEP-0060. This implies that when an
automatic subscriber can specify which event payloads it wants to
receive by including appropriate feature bundles in the XEP-0115
information it broadcasts."
I'd note that this does not mention any distinction between local and
remote subscriptions.
Nothing prevents a more complex client and PEP service using
*explicit* subscriptions, which would not be filtered - basically a
PubSub service which is not only the PEP subset will be severely
broken by your protocol.
In your implementation, because you filter on delivery at the
receiver, you cannot make this distinction, because you lack the
knowledge of the source.
Which means not only is ejabberd's PEP implementation broken WRT
anyone else's, it is *also* self-restricting, such there's no path
forwards to anything more than the PEP subset.
Dave.
