So, probably needs to be a separate event, specifying the format for a particular use case (book, hypernote, online Magazine, etc.)

Like, you could publish something as a series of articles, as an online magazine, or as a document to be downloaded and read on ePaper. You wouldn't necessarily want to formatted identically, everywhere, or using the same title page or cover Image, or whatnot.
You could also reuse format events, or reuse zettles in a different document with different formatting.
Complicated, so v0.3.0.
You can see how difficult it is, just configuring index event tags. 😂
Why do you need an event for the formatting (stylesheet)? Why can't it just **be** the format (file type)? And then you link those PDF's, epubs, etc... to the index event.
You already have a format type (Asciidoc). This is for display or export to other types.
You don't want to have a bunch of event-copies containing different formatting, as you'd then have to change the event content in each copy, to edit it. Nightmare.
