Dear Martin,
this looks great, thank you! - the only downside is that the input to
this grouping attempt is a variable containing the input. So I fear I
can't use <template match="text"> here. I think I would need a new
transformation document in the pipeline with this attempt - which I
would love to avoid. - Or am I mistaken?
Kind regards,
Stefanie

Based on your explanation and the required result I think you should rather
use group-adjacent than group-starting-with.
