I don't think CVS or any other common version control system is really
usable since it doesn't know anything about the inherent tree structure
of XML documents as well as other XML properties like the attribute-or
namespace-order, which is not significant.

We are working on a versioned free XML store called Treetank[1], but
it's not at all ready for a production environment even though we are
concentrating our efforts to clean up our code in the next time.
Furthermore we are working towards a secure Cloud-storage with
encryption of subtrees for different users... I'm currently working on
interactive visualizations of hierarichal diffs, versioned import of
existing XML data and maybe concentrate now my effort on some time-aware
XPath-axis (as XPath extensions) which enable further analysis of the
temporal data.

Maybe TimeMachine from the ETH-Zurich would fit, but since it's also a
research project it may not be ready for a production environment, too.

Sadly I think the versioning aspect itself including branching/merging
of XML seems to be a niche.
