My books tend to use a lot of end-notes. Since I've typically looked at my SIGIL output through Adobe Reader, I never saw any problem with these. But then checking a book in Aquile reader I see they aren't really clickable.
So I tried a test implementation of this syntax:
For the reference in the main text:
xml
<a id="fn1" href="#fn1a" epub:type="noteref"><sup>[1]</sup></a>
For the endnote:
xml
<aside epub:type="footnote" id="fn1a">
<p><a href="#fn1">[1]</a> Endnote text here.</p>
</aside>
Only this doesn't work either, even if I follow the models very closely and only change the file names.
Raising two questions: should SIGIL end note output work in Aquile and most other readers?
If the above syntax is what is required, why does the tool not use it by default? (Clearly adding it for every HTML-style end note would be meticulous).
