I've got an epub with an incorrect mediatype (see discussion in the
Sigil 0.991 thread).
The epub OPF manifest has this entry:
Code:
<item href="Styles/page-template.xpgt" id="pt" media-type="application/vnd.adobe-page-map+xml"/>
FlightCrew says this about that line:
Code:
File: content.opf
Line: 114
Offset: 23784
Message: Error OPF bad item media type value : The <item> element's "media-type" attribute has value "application/vnd.adobe-page-map+xml", but the file's media type is "application/vnd.adobe-page-template+xml". near column 101
but EpubCheck doesn't complain at all. Is this sort of check something that can be added to EpubCheck?
