I gave these a cursory look as I think of the schema as
contrib.

Seems nice to have one. Is anybody worried about the prospect
of committing to some sort of formal documentation of our XML
format?  Do we need to worry about evolving things? (Presumably
such an evolution would be involved anyway since we'd have to
think about backwards compatibility).  I also take it Rado is
volunteering to maintain the schema file if we ever decide we
need to change the format ;-)

The test sounds like a good accompaniment.  Rado, if you'd be
kind enough to amend with the licence boiler plate that'd save
somebody asking you for permission to add it in later.

I'd be a bit concerned about blurring the boundaries between
contrib and the rest of darcs a bit (on the one hand, we're
sort of treating this as a contrib, on the other hand we have
a test for it... which is it?), but I don't think it's a big
deal.  Comments welcome.

[rado] Backward compatibility is really good topic to think about
generally, at least in case of the software with users :)
The XML Schema itself does not help with backward compatibility nor it
makes it worse. But how many mission critical projects use Darcs XML
outputs? For the Haskell projects the Darcs library is much better
choice.

[rado] no problem.

[rado] added.

[rado] you are right. Maybe the better section would be directory with
manual. On the other hand I think the XML Schema and XML-like outputs
from Darcs deserves few cleanups like well formed XML and dedicated
namespace before make it official supported by Darcs Team. 
Anyway I think Darcs Team should spend the effort on more demanded
features. Let keep this XSD in contrib and when XML interface become
demanded, the focus can be allocated on that.

Already reviewed and amended, and looks ok, it's in.
