Hi Christian,
Support for XML Schema is currently out of scope due to other classical database features (incremental indexes, recovery issues, etc); but I agree that schema validation would surely be attractive. As some Open Source features in BaseX have been picked up pace by commercial projects, our focus is shifting now and then, so I can't tell yet what we'll be up to in 6 or 12 months.
Okay, thanks for the clarification.
Kind regards, Ralf
