That's the question. Especially that it also applies to the external
protocol - XEP-0114 which also uses separate namespaces (2!!) for sending
Even though XEP-0225 seems to be re-using jabber:client namespace, which in
my opinion is move in a good direction, it needs some corrections too.
As I mentioned, it doesn't have a separate namespace for the handshaking
packets, hence causing conflicts if you want to put c2s connection manager
behind the XEP-0225 component.
