inclusion of DOI for the EPUB

We can already use DOIs as identifiers in the package document:

<metadata xmlns:dc="http://purl.org/dc/elements/1.1/">
    <dc:identifier id="pub-id">urn:doi:10.1016/j.iheduc.2008.03.001</dc:identifier>
    <meta refines="#pub-id" property="identifier-type" scheme="onix:codelist5">06</meta>
    …
</metadata>

I'm not sure what this might accomplish.

Getting a DOI to link to an EPUB is a separate challenge, which is out of scope.

Thanks @dauwhe! In that case I am closing this as out of scope.
