Problem solved.
I checked OPF specifications (http://www.idpf.org/2007/opf/OPF_2.0...tml#Section2.2) and discovered that language element is required. I had two other required elements (identifier and title) but I was missing the 3rd one.

So, for other people who get the same error: Check that you have all three required elements (identifier, title and language) inside your metadata element.
