Hello,
When I insert a cover in an ePub using eBook Editor version 3.14 , the editor insert in the head of the file content.opf an attribute

Code:

prefix="calibre: https://calibre-ebook.com"

such that

Code:

<package xmlns="http://www.idpf.org/2007/opf" unique-identifier="BookId" version="2.0">

is changed in

Code:

<package xmlns="http://www.idpf.org/2007/opf" unique-identifier="BookId" version="2.0" prefix="calibre: https://calibre-ebook.com">

But epubcheck does not allow an attribute prefix at this place. It's easy to delete this attribute, but why this feature?
Thanks for all.
