I haven't used XSLT 2.0 and am new to 1.0 as you might guess. But if
it is worth the time, I will glady try to rewrite the functionality in
XSLT 2.0.

Well, the current "helping function" is not what I want to do
ultimately. It is merely a counter at the moment, but I'd like to
mimic the behavior of a fold more closely and use a node for the
computation in the helper function. I tried to write this step by
step, and the last one was to add the passing of the node. Does it
make more sense this way? Sorry if it is confusing.

Saxon processes the current stylesheet (with the node passing) in
about 8 seconds (9.5s) if I up the maximum memory again. (Output at
the end: Memory used: 629056248) But I'm not so sure why it'd use so
much memory, the input XML document has about 48mb.
