Possible replacement for EPUBCHECK

[Kayadelenium]

epubveri 0.9.18 is out — four false positives, all found here rather than reported.

The one to upgrade for: a manifest item declared text/html in an EPUB 2 book. Calibre emits these. We treated them as foreign resources, so one real book drew 91 bogus OPF-043 plus a handful of RSC-010/OPF-032. epubcheck warns once (OPF-035) and carries on validating the document — now so do we.

That one cuts both ways: those documents were never being checked at all, so a book of yours may now show new errors that are real — broken links inside them were silently skipped before.

Also fixed:
- A valid TIFF named .png was reported as a corrupt image. It's a wrong extension (PKG-022), not corruption.
- Two extra RSC-005 on ARIA id references — one in EPUB 2, where epubcheck checks nothing, and one duplicate in EPUB*3.

As always — if our output disagrees with epubcheck's on one of your books, both logs as plain text is the most useful thing you can send.

@Kayadeleniu:

I noticed that there still discrepancies between epubveri and EPUBCheck for DNSB's second scrambled book.

epubveri does not flag epub2-only metadata attributes with an opf prefix. For example:

<dc:identifier opf:scheme="calibre">urn:uuid:33f269c3-cb0c-4cab-b952-526cf2a8cad3</dc:identifier>

I also have a suggestion:

Since you apparently develop epuveri and epubsana in parallel, IMHO, it'd be helpful if epuberi displayed an ADV message whenever it finds an issue that epubsana can fix.
