Hi,
I would like to use the group by functionality provided with XQuery 3.0,
along with some other features.
Even though Camel 2.15.2 seems to be using Saxon 9.5.1-5 HE which supports
XQuery 3.0, I'm getting this exception:
Caused by: net.sf.saxon.trans.XPathException: 'group by' is not supported in
XQuery 1.0

Digging further, it seems XQuery 3.0 needs to be explicitly enabled with
Saxon.
Is there any way I can do this, or a possible workaround?
Thanks
