I have been playing around with BaseX today. Nicely done. Unfortunately the do
not support schema validation yet ;-(

I have also been playing with Saxon in Oxygen. I wanted to measure execution
time for different code. However, I have no idea how to measure time in a
declarative language. Can anyone help?

Thanks in advance
