Ah, well.  Turns out that copying the code for \xxx here where \xxx was
a book identifier was not really a good idea before anybody figures out
and defines the difference between a book and a bookpart.  Currently it
is not viable to distinguish them.

\book { \test "surname" }

could conceivably just close its eyes and say "ok, let's treat it as a
book rather than a bookpart" but doesn't.  Does anybody have an idea
what is supposed to distinguish a book from a bookpart outside of actual

\book {
  \bookpart { ... } }

usage?
