compatible with EPUB2 readers? #22

Open dportabella opened 1 year ago

dportabella commented 1 year ago

are these EPUB3 examples backward compatible with EPUB2 readers?

Generally, no, but the ones with an NCX should be reasonably usable in EPUB 2 reading systems (provided they'll open publications with a 3.0 identifier).
