xml-stream

See <URL:http://etherx.jabber.org/streams/> for more about simple
XML streams.

Generally speaking, elements directly under your <stream:stream/>
should be reasonably small.

Sample usage:

(require 'xml-stream)

(defun my-xs-callback (thingy &rest args) ...)

(setq my-xs-stream
      (xml-stream-open-network-stream "Hello" "*hello*"
                                      "floobin.cx" 4732
                                      '((xmlns . "hello"))
                                      'my-xs-callback
                                      arg1 arg2 ... argN)
...
(xml-stream-send my-xs-stream '(hello nil "world"))
...
(xml-stream-close my-xs-stream)
