Ok, here's some more information. I'm running Pandoc 2.7.3 on macOS 10.14.6.
My custom template hasn't been modified in the header area:
$pagetitle$
I have a file called book-variables.yaml that looks like this:
---
lang: ja
title:
- type: main
text: "Wow a book"
creator:
- role: author
text: "Me"
language: ja
identifier:
- scheme: DOI
text: doi:10.234234.234/33
ibooks:
version: 1.3.4
page-progression-direction: ltr
---
And I am using the command:
/usr/local/bin/pandoc mybook_epub_apple_4pandoc /Users/me/Library/
MobileDocuments/com~apple~CloudDocs/book-variables.yaml -o mybook.epub --
from=markdown-smart --to=epub-smart --toc --toc-depth=3 --epub-
chapter-level=2 -M date=2019-10-31 --css epub.css --resource
-path .:/Users/me/Library/MobileDocuments/com~apple~CloudDocs/audio --epub-
cover-image=cover.jpg --template mytemplate.epub3 &>
epub_apple_pandoc_errors.txt
With this setup, cover.xhtml and title_page.xhtml have the language set on
the HTML tag, but none of the chapter files do. (ch001.xhtml, etc.)
