After contemplating over http://www.idpf.org/epub/30/spec/epub30-publications.html#sec-opf-dcidentifier I finally found a solution that validates with epubcheck The value of epub_identifier did not cause the errors but the value of epub_id. epub_id is the internal reference for the dc:identifier metadata. The example on the idpf site shows it: <package … unique-identifier="pub-id"> <metadata xmlns:dc="http://purl.org/dc/elements/1.1/";> <dc:identifier id="pub-id">urn:uuid:A1B0D67E-2E81-4DF5-9E67-A64CBE366809</dc:identifier> … </metadata> </package> So here the string "pub-id" is the unique-identifier of the metadata that gives the identifier "urn:uuid..." I used "pub-id" and "website" as unique-identifier, both were validated. I did not find a list of good XML names for unique-identifier. For now I'll stick to pub-id. The default of Sphinx is an empty string which does not validate. Maybe we should consider to default to pub-id?
