Hi everyone,

as the title suggests, I'm here because I'd need to use role="doc-glossary" on the <aside> tag. However, both EPUBCheck and ACE report errors. ACE reports that "ARIA role doc-glossary is not allowed for given element". As far as I understand, <aside> has the implicit role "complementary", which is a subclass role of "landmark", which in turn is the superclass indicated for doc-glossary.

Also, looking at the Accessible Publishing Knowledge Base by DAISY, <aside> is listed among the possible elements doc-glossary is allowed on (http://kb.daisy.org/publishing/docs/html/dpub-aria/doc-glossary.html).

As for the content of the <aside>, the error occurs both if we have a definition list (<dl> with <dt> and <dd>, possibly with role="term" on <dt>), or if we have a <p> with <dfn> to identify the term.

In the specific use case, I have an EPUB with boxes (<aside>) that contain definitions of words and therefore represent small glossaries, so using doc-glossary would give more semantics.

Can anyone help me understand the problem?
