Based on a recommendation I validated some ebooks with Flightcrew. These ebookes were created with Sigil, nevertheless Flightcrew showed many errors. All of them were related to areas which were automatically generated by Sigil, i.e. toc, spine etc.
Then I validated the same book with epubcheck and it passed without errors. So it looks like Sigil and Flightcrew don't apply the same standards.
So now I'm not sure: is an epub OK if it passes epubcheck or is it just "tolerable?
