In Mikes' JNG, it's actually no longer strictly necessary (only
preferable) for routers to check the well-formedness of XML payloads
that they don't actually have to parse, because with proper framing,
transmitting malformed XML no longer necessarily causes a
transport-layer disengagement.

That stated, Oliver outlined the good, open questions related to
factoring addressing out of the XML envelope, which are mostly the same
reasons I'm not doing it in the proof-of-concept.

XML is a document format, not a transport, and not a wire protocol. It's
a wonderful document format, but we're kidding ourselves by trying to
use it for either of the latter, because it's just awful for those

By the way, we're not the only ones having this problem; you might want
to see SOAP Attachments.

My money says they came to Jabber because of its open-source aura and
the fact that it uses XML at all, not because it has an XML-only wire

Get over this notion that I'm dumping XML. I'm not. I'm sprinkling 4
bytes here and there that vastly simplify things for the machine.
Everything else that's not a binary attachment is XML.
