Hi,

Yes, I think that being able to run queries against versioned data is one of the main motivations for having a versioning system tailored to XML.

The XQuery world provides a very good basis for this: for instance, the XQuery Update Facility defines Pending Update Lists, and these are perfect for diffs. Also, the XQuery and XPath Data Model has the concept of node identity, of which the versioning system can keep track.

Kind regards,
Ghislain
