ePub synthetic spread export not including xml / html language tags
Version 21.0
When exporting a Fixed Layout EPUB with the <Enable Synthetic Spreads> option, the language tags are not exporting in the HTML, which is an issue for accessibility. The language tags ARE exported properly when the <Convert Spread to Landscape Page> option is chosen, so this clearly seems to be a glitch with this particular export option.
I would expect the following code to be at the top of each of the HTML files <html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en" xmlns:epub="http://www.idpf.org/2007/ops">, and this at the top of the OPF file: <package xmlns="http://www.idpf.org/2007/opf" version="3.0" unique-identifier="bookid" prefix="ibooks: http://vocabulary.itunes.apple.com/rdf/ibooks/vocabulary-extensions-1.0/" xml:lang="en">
However, the exported files have the following code, which misses the xml language tags:
HTML: <html xmlns="http://www.w3.org/1999/xhtml" xmlns:epub="http://www.idpf.org/2007/ops">
OPF: <package xmlns="http://www.idpf.org/2007/opf" version="3.0" unique-identifier="bookid" prefix="ibooks: http://vocabulary.itunes.apple.com/rdf/ibooks/vocabulary-extensions-1.0/">
This is causing a LOT of manual work for my team and turning into a big time suck. It seems like something that could be a relatively easy fix on the development side... so we'd REALLY appreciate you prioritizing it! Especially with the recent EAA guidelines for ePub accessibility, this is a critical aspect of the ePub export.
