As I said, there must be some missing required items. Add in the standard metadata items in Sigil, and I think you'll find that the errors will go away.
(In XML, there can be required elements. If they're not present, the XML isn't valid.) |

Problem solved.
I checked OPF specifications (http://www.idpf.org/2007/opf/OPF_2.0...tml#Section2.2) and discovered that language element is required. I had two other required elements (identifier and title) but I was missing the 3rd one. So, for other people who get the same error: Check that you have all three required elements (identifier, title and language) inside your metadata element. |
