The problem isn't so much in the parser.

XML is well-formed data.  A parser is _supposed_ to reject data that is
not well formed.  This is generally is a good idea, and is one of the
main tenets of the XML standard.

There's no real way to parse an xml document on the fly, while
maintaining it's well-formed-ness.  We'd have to make each bit a
standalone document.  That doesn't make a whole lot of sense, and
probably increases the overhead too.

Jabber, from what I can tell, wrote their own customer parser, because
they used XML for messaging.  What they have now isn't XML but looks
like XML.

And we all came to the general consensus before that if it wasn't going
to be real XML, why make it XML at all?

But maybe our assuptions aren't true.  How do SOAP and XMLRPC work?
These would seem to be streaming protocols or at least similar to how
Jabber works, and I assume they are conformant to the XML spec.
