This may address some of our concerns, too. We work with HTML files that
represent book chapters. Given that the same source may end up in ebooks
as well as various print editions, we prefer to keep the source "clean"
and use different CSS files for the different presentations. Having a
separate HTML template with presentational information would allow us to
continue with the single content source without resorting to external
processing.

Yep. Luckily PrinceXML ignores this restriction on the content property,
and we find it really useful to entirely replace some elements. Our source
HTML may contain "space breaks" [1] with three asterisks to indicate a
change of scene in a novel. We may replace those asterisks with some
font-based ornament or image in the printed version but not the ebook
version. That's really easy using content on the element.
