As Doitsu said, Sigil's F7 is not a compliance or specification checker. It's purpose is to make sure the html can be safely parsed with no data loss. Tags are properly closed ... tags are properly nested. That's it. All epub or (x)html specification checking is left to plugins (or external tools). Been that way tor the entire 0.9.x series.

Again: Passing Sigil's "Well-Formedness" check (F7) does not mean, "my EPUB is A-OK". It means "I can safely run automated tools and plugins on the xhtml in my EPUB."

No EPUB should be assumed to be error-free unless checked using EpubCheck (website, command-line tool, or plugin) and/or FlightCrew (plugin).
