According to the XEP-0060 spec, this is an optional feature. It just happens to be one that would simplify my life quite a bit
When I submit a disco items request to a leaf node, I always get an empty query element in the response, even when that node has items (as proven by browsing the mysql database and by simply requesting all items).
The reason I ask is that the empty query element response is somewhat ambiguous, does it mean that this is unsupported? It seems to be implemented in the PubSubModule.java source.
Maybe my server or client setup is somehow broken. If this isn’t expected I can provide any code examples or config data that would be helpful.
