this would be an engraver placed in the score context, that does this
processing inside the finalize slot.

If you look in "edition.scm" lines 480 following in my lalily project,
you find an annotation engraver, that does it this way. There is a music
function \todo "<short>" "<description>" that inserts the annotation in
the music as a TextScript with an annotation properties, which is
fetched by the engraver.
At the bottom of the file, you can place
\markuplist \annolist
to display the annotations in the pdf.
And there is also a "*-todo.log" file created.
Just a this-is-how-I-didit ;)

Best, Jan-Peter
