I'm trying to publish a book of short sheet music pieces exported from a music notation program that provides export to epub 3 format. The problem is that the export process leaves a bunch of validation errors and although the music shows up perfectly on my iPad when I load the epub onto it the same file will not pass Apple's validator. I have solved a few of the errors on my own but can't figure out how to do the two that I am pasting below.

I am also providing a copy of the exported contents.opf, nav.xhtml, and the first page p001.html of the document in a zip file attached to this post.

First error is:
ERROR ITMS-9000: "ChristmasCarolsAltoSaxIBookv3.epub: OEBPS/content.opf(24): assertion failed:
media overlay items must be of the 'application/smil+xml' type (given type was ''). This error occurs 39 times." at Book (MZItmspBookPackage)

Second error is:
ERROR ITMS-9000: "ChristmasCarolsAltoSaxIBookv3.epub: OEBPS/content.opf(21): assertion failed:
global media:duration meta element not set" at Book (MZItmspBookPackage)


There are actually a couple more errors as well but I didn't want to burden anyone with a really long post. Any help would be greatly appreciated!
