Hi, I posted about this in the epub section but I'm thinking that it might be more of a Calibre issue?

After I used Calibre to convert my epub and ran it through the epub validator I got this error report

ERROR: isbn.epub/content.opf(12): attribute "opf:file-as" not allowed here; expected attribute "id" or "xml:lang"

I have tried taking out the "opf:file" bits of the code but that doesn't seem to help. Here is a sample of the code

<?xml version="1.0"  encoding="UTF-8"?>

Any help with this would be great!
