It was group-starting-with in the posted code, both the original and the
suggestion I made (actually the code I spelled out used only
group-starting-with but I also said that the existence of start and end
marker elements kind of asked for the group-starting-with to wrap a
group-ending-with.

What's the point of that if the input has chapter start and end marker
elements like shown in the original post with e.g.


<root>
 B B B  <div type="book" sID="book1">
 B B B B B B B  <chapter sID="chapter1" n="1"/>
 B B B B B B B  <p sID="p1.1" n="1"/>Paragraph 1 text.
 B B B B B B B  <p eID="p1.1"/>
 B B B B B B B  <p sID="p1.2" n="2"/>Paragraph 2 text with
<emphasis>emphasis</emphasis> added.
 B B B B B B B  <p eID="p1.2"/>
 B B B B B B B  <p sID="p1.3" n="3"/>Paragraph 3 text.
 B B B B B B B  <p eID="p1.3"/>
 B B B B B B B  <chapter eID="chapter1" n="1"/>
