While requesting disco#items on a PubSub service, an entity might want to only get nodes of certain pubsub#type. To do so, it may add a filter child of namespace urn:xmpp:pubsub-filter:0 to the query element, containing a &xep0004; form with FORM_TYPE set to urn:xmpp:pubsub-filter:0 and an allowed-types or blocked-types list-multi type field containing the various types it wants to filter.

-When allowed-types is specified, a PubSub service MUST return nodes of matching pubsub#type in its response.
+When included-types is specified, a PubSub service MUST return nodes of matching pubsub#type in its response.
-When blocked-types is specified, a PubSub service MUST return every node but those of matching pubsub#types in its response.
+When excluded-types is specified, a PubSub service MUST return every node but those of matching pubsub#types in its response.
-Both allowed and blocked fields MAY contain an empty value to designate nodes with an empty pubsub#type.
+Both included and excluded fields MAY contain an empty value to designate nodes with an empty pubsub#type.
If both the allowed and blocked fields are specified, a service MUST return an error of type modify containing a bad-request element in the urn:ietf:params:xml:ns:xmpp-stanzas namespace.
