You are right that both approaches don't have what I was looking for: A 
pre-cooked solution for writing CSV rows and cells. But that's OK, now I 
have what I need and at the same time I have learned some useful things.

That's completely true. I'm familiar (and happy) with the space 
insertion rules of XSLT 2.0 (if I may use this non-technical term here), 
but still have to wrap my head around the way XQuery serializes the 
results of multiple iterations.

Unfortunately not: Of course, string-join's separator character (here: 
line feed) is by definition not to be appended after the last item. 
That's why changing the functions doesn't work out.
