Michael, a negative XQuery scenario I encountered by accidient. I haven't double
checked, it might well be a known problem in Saxon 8.1.1. declare namespace foo =
"foo"; foo:unknown() -> java.lang.NullPointerException at

Thanks for reporting it. It's already fixed, though I've now added it to the bug
register. (The error is detected and reported at compile time, but Saxon then attempts
to execute the query regardless, at which point it falls over.)
