- * A SAX XML parser that builds XML nodes and spawns events when a complete
- * stanza is received (an element of level 2), or when the document is
- * opened/closed (an element of level 1)
- *
- * After a stanza_event has been spawned, we delete the whole stanza. This
- * means that even with a very long document (in XMPP the document is
- * potentially infinite), the memory is never exhausted as long as each
- * stanza is reasonnably short.
- *
- * The element names generated by expat contain the namespace of the
- * element, a colon (':') and then the actual name of the element. To get
- * an element "x" with a namespace of "http://jabber.org/protocol/muc", you
- * just look for an XmlNode named "http://jabber.org/protocol/muc:x"
- *
- * TODO: enforce the size-limit for the stanza (limit the number of childs
- * it can contain). For example forbid the parser going further than level
- * 20 (arbitrary number here), and each XML node to have more than 15 childs
- * (arbitrary number again).
