EPUBCheck v4.2.0 gives a warning for generated nav #81

Closed taroxd closed 5 years ago

taroxd commented 5 years ago

WARNING(RSC-017): path/to/epub/OEBPS/nav.xhtml(3,9): Warning while parsing file: The 'head' element should have a 'title' child element.

Maybe a title element should be added to head for automatically generated nav file?
