PubSub <subscriptions node="someNode" /> results problem

When my client is connected to an OpenFire server and I send the following stanza:

  <pubsub xmlns="[http://jabber.org/protocol/pubsub](http://jabber.org/protocol/pubsub)">

I should get back a resulting stanza containing all of my subscriptions to someLeafNode. . .but instead I get all the nodes that I’m subscribed to:

 <pubsub xmlns="[http://jabber.org/protocol/pubsub](http://jabber.org/protocol/pubsub)">

Am I reading XEP-0060 correctly, or is this an OPTIONAL implementation that’s not implemented in OpenFire?

See XEP-0060 section 5.6 Retrieve Subscriptions Examples 24 and 25
