RE: possible? for-each-group inside a for-each-group

Yes. it's absolutely possible. You can nest for-each-group statically, or
dynamically, or both. I often nest it recursively.

Since every item in the population is a par element with
@class='Entsch_normal', including this in your starting-with condition is
rather redundant.

Normally the inner grouping will select all the items in the outer group.
select="*" selects the children of the context item, which is the first item
in the current group. The most common usage is to use
select="current-group()" in the inner grouping. Perhaps you want
select="current-group()/* - but I'm not sure, I don't understand your
requirements well enough.
