ERROR ITMS-9000 in submission

Hi everyone

This is the first time I submit a book to Apple and during submission I see this error

ERROR ITMS-9000: "saigon.epub: OPS/section-0009.html(87): attribute "value" not allowed here; expected attribute "dir", "id", "lang", "style", "title" or "xml:lang". This error occurs 339 times." at Book (MZItmspBookPackage)

I use Jutoh to convert Word file to epub. Would you please help me out to resolve it? Thanks for your help
