Hi again!
I'll certainly make a PR, but I'm waiting for a while, to:
- give others an opportunity to provide feedback
- find out, while I continue working down the XEP, if there are other
things that I'd like to address.
One such 'other thing' is this:
XEP-0060 in section 4.6 defines two forms of addressing: JID and
JID+NodeID. It states the JID format SHOULD be used when using a protocol
that does not support the node attribute. However, it does not explicitly
prohibit the JID format from being used if the protocol _does_ support the
node attribute, right?
I believe that this leaves the door open to using the JID address format
with Service Discovery. Unless I'm mistaken, this is then a valid
equivalent of example 10:
<iq type='result'
from='pubsub.shakespeare.lit'
to='francisco(a)denmark.lit/barracks'
id='nodes1'>
<query xmlns='http://jabber.org/protocol/disco#items'>
<item jid='pubsub.shakespeare.lit/blogs'
name='Weblog updates'/>
<item jid='pubsub.shakespeare.lit/news'
name='News and announcements'/>
</query>
</iq>
This seems to be indistinguishable from a response that discovers items
(rather than nodes) as specified in section 5.5.
Using JID+NodeID in a protocol that supports the node attribute seems a
silly thing to do to me, but I don't think it is forbidden by the XEP.
Should we add a restriction (or at least a recommendation)?
Kind regards,
Guus

Hi Guus,
We're in agreement, I think. I do prefer
example 11 to be removed. Your
argument of keeping it is based on it being used to discover _items_.
That
practice (discovering items) is not defined in
section 5.2. Instead, that
is in section 5.5. Section 5.5 already has an appropriate example).
You're right, items discovery is only mentioned at the end of §5.2, and
§5.5
describes it. So example 11 can be removed too.
Regarding hierarchy, XEP-0496 and XEP-0499 are explicitly backward
compatible,
meaning that all nodes are returned if extended discovery is not used. So
we
can remove the notion of "first-level nodes" from the description of
example 10
(except if we want to keep it due to XEP-0248).
Will you make a PR for those changes? For a stable XEP it will have to go
through council, and authors input would be good to have too.
Best,
Goffi_______________________________________________
