eXist is working towards full XPath and XQuery 3.0 compliance and we
already implement most of this. eXist is open source under LGPL 2.1

Whilst eXist can run as a standalone database you can also use it as
an embeddable library in your own Java applications and it will allow
you to execute XPath 3, XQuery 3 and XSLT 2.

you'll have to buy a license for them and that will cost many yy thousands of

capability in Java and distribute it for free to the people in the field."
