Sends an event notification for the last published item of each leaf node under the
root collection node to the recipient JID. If the recipient is not the owner of this service,
has no subscription to the root collection node, has not yet been authorized, or is pending to be
configured -- then no notifications are going to be sent.<p>

Depending on the subscription configuration the event notifications may or may not have
a payload, may not be sent if a keyword (i.e. filter) was defined and it was not matched.

An optional filter for nodes to be processed can be provided in the second argument to this method. When non-null
only the nodes that match an ID in the argument will be processed.

@param recipientJID the recipient that is to receive the last published item notifications.
@param nodeIdFilter An optional filter of nodes to process (only IDs that are included in the filter are processed).
