You can lead a horse to water but you can’t legislate kindness.

Many early “fixed layout” books were magazines using bitmap images,
e.g. originally made for the iPad. There’s not necessarily any
“complete information” in them, short of using OCR.

So the result is that people add dummy information, lorem ipsum, your
browser isn’t capable, if you force them to add content they don’t
have.

You do say,

and that may be true but not very useful.

For new books going forward, epubcheck could maybe do more.

For sure. Actually if HTML/CSS had better support for poetry you might
not need fixed layout here, but there would always be other examples.

What’s needed is responsive ebooks and responsive, accessible, SVG.
