   * `IQProvider` -- parses IQ requests into Java objects.
   * `Extension Provider` -- parses XML sub-documents attached to packets into PacketExtension instances. By default, Smack only knows how to process a few standard packets and sub-packets that are in a few namespaces such as:

 passed to the correct provider. Each provider must implement the
