iTunes Producer "package.opf" error

[MatMu]

Hello,

I'm new so I hope this is the right section to post this.
I'm running into an error I was not able to fix, while trying to upload my epub book in iTunes producer.

here is the two errors I'm getting:

"Package Summary:

1 package(s) were not uploaded because they had problems:
/Users/Me/Desktop/Portraits.itmsp - Error Messages:
ERROR ITMS-9000: "Portraits.epub: /Users/Me/Desktop/Portraits.itmsp/Portraits.epub/EPUB/package.opf(4): [RSC-005] Erreur lors de l'analyse du fichier 'lattribut {0} nest pas autorisé ici ; lattribut {0} est attendu'.. This error occurs 4 times. (For more information refer to http://support.apple.com/kb/HT6213)" at Book/BookAssets
ERROR ITMS-9000: "Portraits.epub: /Users/Me/Desktop/Portraits.itmsp/Portraits.epub/EPUB/Navigation/nav.xhtml(13): [RSC-005] Erreur lors de l'analyse du fichier 'lélément {0} est incomplet {1}'. (For more information refer to http://support.apple.com/kb/HT6213)" at Book/BookAssets

and this is the 4 first lines of opf using calibre 2.3

<?xml version="1.0" encoding="UTF-8"?>
<package xmlns="http://www.idpf.org/2007/opf" xml:lang="fr" prefix="rendition: http://www.idpf.org/vocab/rendition/#" unique-identifier="uid" version="3.0">
<metadata xmlns:dc="http://purl.org/dc/elements/1.1/">
<dc:title id="id-1">Portraits</dc:title>

can someone please help me????

Has the epub passed epubcheck? It also appears to be an ePub3... If that is intentional, make sure you identify it as such when you upload it. Sorry I don't know any more about itunes upload procedures - I refuse to buy a mac just to upload to their server.

it was indeed a conflict between epub2 and 3, thank for showing me the right direction!
