Is it allowable to add a lang= bit to the HTML line of the jacket in the Editor? Unless it's just a function of something I've done, that line in the current book I'm editing is:
Code:
<html xmlns="http://www.w3.org/1999/xhtml">
I'd like to add the language stuff so it looks something like:
Code:
<html xmlns="http://www.w3.org/1999/xhtml" lang="en-us" xml:lang="en-us">
And, while I'm asking, what about the xmlns:epub= bit? IOW:
Code:
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:epub="http://www.idpf.org/2007/ops" lang="en-us" xml:lang="en-us">
Can I, should I, manually change that? Is there a setting in Calibre to do that in the conversion/polish process?
