For the record, this is what the generated LaTeX fragment look like:
% -------
% Chapter
% -------
\chapter{First chapter title}
\label{first-chapter}\hyperlabel{first-chapter}%
First chapter Author
First chapter, first paragraph.
Looking for solutions, I came across

and
<URL:

which might inspire a good way to solve this.
