Nobody sends ill-formed XML because nobody accepts it, and what use is a client or server that nobody can receive messages from? I think this is ideal; bad producers never have a chance to enter the ecosystem. This unfortunate oversight in the original RFC has spoiled that, but we can still fix it. Even if it takes years for most server deployments to be updated, I'm expecting XMPP to be around for decades (centuries?). The alternative (limiting what parsers non-toy clients can use, maybe even requiring them to write their own or use liberal "XML" parsers) is ugly. I don't want XMPP to end up like HTML. (though I doubt it would ever get *that* bad :)) Also keep in mind that in this context "servers" only means the actual stanza router; having to handle namespace ill-formed XML beyond rejecting it complicates things for component developers too.
