I've recently noticed that when converting from .odt to epub, I'm getting the following at the top of each html file:
Code:
<?xml version='1.0' encoding='utf-8'?>
<html xmlns="http://www.w3.org/1999/xhtml" class="calibre">
I don't know exactly when I first noticed this; I'm now on 5.16 (Ubuntu 20.04) and it's still there.
Can someone tell me if a class code actually belongs there? Or is this a bug?
Thanks!
