Im getting a lot of meta properties in the .opf file but per apple standards it will not validate and I was curious to know why?? I cant find any solid research on this so I thought id ask.
example:
Code:
<opf:meta property="dcterms:modified">
2012-04-12T12:00:00Z
</opf:meta>
I would say its a date tag but they already have it written in here as:
Code:
<dc:date>2012</dc:date>
