just received an answer from Smashwords, and actually, proud to say, I was right !
Many epub 3 functionalities are not accepted by Smashwords (this includes footnotes pop up, which was one of the main thing rejected in my ebooks) ...
So their standard is not real epub 3 but something like epub 2.5 (I know it doesn't exist, but well ... )

If in a recent version of Sigil, it will tell you if your epub is an epub3 or epub2 by looking at the main gui Window name.

Yes, I'm using the latest update of Sigil, always, and by default using the epub 3 option which result in properly tagged xhtml files.
