ejabberd has no collection nodes but "normal nodes" that are not "leaf 
nodes" and not "collection nodes".
This nodes have "normal nodes" and "items" as child nodes.

A "normal node" does not exist - if I understand your answer.
In my question - because I thought that it is NOT a bug - I asked "NOT a 

If it is a bug, this makes no sense for me.
Why have collection nodes and leaf nodes?
Why not unify that?

In a filesystem there are directories and files.
In pubsub we have "directories", "files" and "items".
"directories" are spezial files - in XML world we don't need that.

Think about mapping XML - PubSub subTree.

Or navigation through a pubsub graph.
Do we really need a leaf node the is called "index.pubsub" (like 
index.html) ?

Think about a hierachical wikipedia like system. Sometimes it is 
nessessary to extend things.
XML is extensible.

A "node" is not extensible if it is not possible to make a child node of 
this node.
A "leaf node" is the "item" I thought.
