EPUBCheck from W3C is throwing a lot of errors on a converted .docx to epub 2 file:
Referring to a footnote:
Code:
<a role="doc-noteref"
Code:
ERROR(RSC-005): book.epub/index_split_051.html(58,494): Validierungsfehler: Attribut "role" ist an diesem Element nicht erlaubt. Erlaubt ist nur das Attribut "accesskey", "charset", "coords", "dir", "hreflang", "lang", "rel", "rev", "shape", "style", "tabindex", "target", "type" oder "xml:lang"
I am surprised that the conversion tool seems to produce invalid epub2 xhtml?
Is this something that I should care about and correct or does it not matter?
