As far as I know, most XQuery processors (such as ours) currently rely on
Charles Foster’s XQJ implementation.
In the past, we had our own implementations, but we stopped maintaining it
some years ago. Users keep asking us why they cannot use XQuery 3.1 with
XQJ; due to the unfortunate licensing conditions you mentioned, we didn’t
invest more time in this.
