How? You would doubtless agree that mandating a specific encoding for all streams sidesteps one of the major benefits of XML. Introducing an encoding declaration mechanism into the transport protocol, as HTTP does, would duplicate the function of the XML processor. But if you have a specific solution that I've missed then I'm sure I can appreciate it. > No, it still looks like a messy architecture to me, because the > transport layer has to know about the packets -- it has to parse the > XML about to get information about what it's looking at, and that adds > complexity and inefficiency.

I think it's supremely elegant that only the XML processor needs to look at data coming off the wire. It's also as efficient as it gets. Of course the software architecture that handles the documents emitted must be modular and extensible, but the task of parsing is done. Tom Harding xml-dev: A list for W3C XML Developers.
