The disco#info request is sent by the requesting entity to the generating entity. The value of the 'to' attribute MUST be the exact JID of the generating entity, which in the case of a client will be the full JID &LOCALFULL;.
- +Note: The generating entity SHOULD NOT include the "caps node" in the list of entities it returns in its disco#items responses; i.e., the caps node is a kind of virtual or phantom node, not a true items node that is associated with the generating entity for service discovery purposes.
The disco 'node' attribute MUST be included for backwards-compatibility. The value of the 'node' attribute SHOULD be generated by concatenating the value of the caps 'node' attribute (e.g., "http://code.google.com/p/exodus") as provided by the generating entity, the "#" character, and the value of the caps 'ver' attribute (e.g., "QgayPKawpkPSDYmwT/WM94uAlu0=") as provided by the generating entity.
The generating entity then returns all of the capabilities it supports.
