Ah, now you're just reminding how long it has been since I've published anything. I hadn't bothered to keep the plugins going because for the last few years I've only been tweaking stuff I buy.

You are, of course, correct. The epubcheck plugin does report that error, plus another from the opf.

ERROR(OPF-014): The property "scripted" should be declared in the OPF file.

ERROR(RSC-005): Error while parsing file: character content of element "dc:language" invalid; must be an RFC 3066 language identifier


There were also errors in the ncx and nav.xhtml files. This is a new release ebook. It warms the heart to see how much care the traditional publishers take with their work.
