According to the JEP, all of the data transfers are sent using the same ID,
and are all IQ-sets. I would argue, that the receiving entity responds with
an IQ-result when it receives the iq with the <close> element and after it's
received all of the sequenced packets. This makes more sense to me since all
of the individual iq-sets are just part of a larger "transaction".

I'd like to see that response added into the JEP and the semantics around
whether or not that stanza is a result or an error. Given the nature of
delivery in jabber, it's unlikely that the receiver would not recieve one of
the stanzas with data, but I suppose it's possible. There should be some
errors around this.

Nice progress on this simple JEP though.
