That meta entry looks like it belongs in an EPUB3 to me, not and EPUB2 - which is what your epub appears to be.
I found that code requirement in their Asset Book:
Quote:
If you intend to provide embedded fonts in a Flowing Book or a Fixed Layout Book, you must set the "specified-fonts" option to true. See “Defining Book Layout Metadata” (page 56).
and then:

Quote:
ibooks:specified-fonts
Example:
<meta property="ibooks:specified-fonts">true</meta>
Must be defined if your book contains embedded fonts. This is equivalent to specified-fonts : true|false in EPUB 2.
I think I misread it, then. I should be adding the "specified-fonts : true|false" in the ePub2. But what, exactly, is the line of code? I found this online:

Code:
<option name="specified-fonts">true</option>
But where does it go? In the metadata of the content.opf? I added it there and the file passes validation. but it this correct?
