Thanks for the input and advice.

Tex2009ans:

So "EPUB-Checker", you actually mean epubcheck:

I am using the app version which has in the toolbar: "pagina EPUB-Checker", and in the body of the window under "Validate EPUB": "(EPUBCheck 4.2.2).

But to my knowledge, the most well-supported type is epub:type="footnote"

I think you are correct. Everywhere I look, including the Apple site, they always use footnote/s, plus, using those terms appears to take away the alert.

To read more on the topic, see the 2016 topic "Epub3 Foot- End-notes", especially my Post #39+ where I disuses the disadvantages of <ol> (and similar).

Your first link failed. I checked out the other.

Where do I go to get all the fallbacks required! I've been trying to follow the line of Jiminy Panoz and the Blitz framework.

Hmmm... strange. Mind pointing me to those posts?

I tried to go back and find where the lists were recommended (and did another search), but I think it must have been on other sites such as Stackoverflow, Github etc. — and they appeared to be experienced). Anyway, so, ol and ul lists don't work? That seems to be the opposite to the presenter at the Ebookcraft 2019 recommended by Tex2009ans above [see around 19.55]. Her point at that stage was don't rely on CSSS, but just basic HTML and her whole point (it seemed to me) was that the person who didn't use a the list tag ended up with bad presentation when the CSS was removed. I have to admit, I am confused about this.

DiapDealer:

It is my opinion that ol and ul elements are best left to non-ebook usage. They offer little benefit (and plenty of disadvantages) to static content to be rendered by multiple ebook readers/apps. Numbers and bullets are not that difficult to code/style manually when you only have to do it once. It'd be different if one was building dynamic content from database records.

Thanks for the advice. As mentioned in the last comment to Tex2009ans above, the presenter at Ebookcraft 2019 seemed to be saying the opposite, but I may have it wrong.

I would very much appreciate being pointed in the right direction for finding a list of all the pitfalls and fallback needs. I know that's not going to come in one place, but if anyone can point me to any resources that would help me get up to speed in a reasonable time without having to crawl through mountains of posts and websites (which has been my experience so far), I'd be grateful!
