xml-dev - What is XP?

[Dave Winer <dave@userland.com>]

Just curious.. I wonder if XP is at the stage yet where there's a statement
of how it will differ from SOAP and XML-RPC? I've caught a wiff of a debate
about how it compares to ebXML, but I'm not so sure I get what ebXML is. I
know what SOAP and XML-RPC are. Dave
