I don't have much to add to what Bart said, though I'd like to echo his
point that we're very interested in supporting this work. (I think it'd
be a lot easier to implement xcb-server inside an existing server like
X.org, but you can do it however you want. *grin*)

Everything in the X wire protocol is described in the XML already, so
while I'm not sure I understand the question, I think the answer is that
you shouldn't need to do that.

That sounds about right.

I've had this idea for a while, though, that there are some interesting
games you can play if xcb-server is a thin layer that dispatches into
functions named identically to the xcb-client functions. Then (with a
little bit of extra glue) you can link an XCB app directly into the X
server, which I think might be useful under some limited circumstances.

The practical side of that is it'd be nice if you generate code that
uses names and argument lists roughly identical to the ones XCB uses
now. Otherwise it should probably have no effect on your work.
