Yes, I was coming to the same conclusion. Your code appears to be
essentially correct but has run out of stack space. Saxon should be able to
handle this with a technique called tail call optimization - your recursive
call is the last thing the function does, so the optimizer should turn it
into a loop. It's not clear to me at first sight why this isn't happening.
If you can send me the required files I'll take a look at it, though it may
not be for a few days.
