I was validating an epub and the epub had a weird date coded within the opf I have not seen before.
Code:
<dc:date xsi:type="dcterms:W3CDTF">2012-10</dc:date>
If I remove the xsi:type="dcterms:W3CDTF the line will validate but Im having trouble finding exactly what does that mean. Can anyone share light on this?
