I just submitted
https://github.com/xsf/xeps/pull/1426
with a rendered
version at
https://nicoco.fr/inbox/spaces.html
Fetching the list of rooms that are children of a space is done via a
disco#items directed at the JID of the space on the urn:xmpp:spaces:0 node.
Using a node on top of the JID makes it possible for a space to be a room
itself, which is possible but not required by this specification.
I don't think using a node is needed to fulfill this requirement. Any MUCs
found as items on a MUC would be members surely? And any items on a space
JID would be items in that space surely.
If we decide a node *is* needed, I think the node needs a name related to
what it is. Naming the node the same name you suggest for a list of spaces
to list the items in a space is confusing IMO.
