Saxon-HE 9.8.0-3 is out but still problems are there.
See Incorrect behavior in Saxon-HE-9.8.0-3 (maven).
Another problem is that we see that something has propably happened with tail call optimization. Code that was working earlier now give an error:
err:SXLM0001: Too many nested function calls. May be due to infinite recursion.
We have to figure out how to build a simple TC for Michael Kay to test it.
