<p>This protocol is intended primarily for clients with human interaction. Due to the open-ended nature of
the possible optimisations implemented by the server, it may not be suitable for non-IM purposes where the
fully standard behaviour of XMPP is required.</p>
<section2 topic="In-order processing" anchor="in-order-processing">
<p>
XMPP requires stanzas to be processed in order as per &rfc6120; 10.1. Especially "If the server's processing of a particular request could have an effect on its processing of subsequent data it might receive over that input stream..., it MUST suspend processing of subsequent data until it has processed the request.". As a result, all actions triggered by a CSI nonza sent to the server must happen before processing further requests from the same client to the server.
</p>
<p>
For example: A client sends a CSI active nonza, followed by an XMPP Ping request to the server. The server first changes the CSI state to active and flushes all eventually queued stanzsa. After the state has been restored to 'active' and
all resulting stanzas have been put on the wire, the
server sends the pong.
