Great! These are useful additions.

I feel the removing epub3 attribute is needed to discuss the necessity and how to switch.

I agree, here are a few things to consider during this forced conversion:

1. replace section tag with <div data-tag="section"> and similar for closing tag
2. replace epub:type=blah" attributes with data-epub-type="blah" to keep the semantic meaning
3. allow video and audio tags to go through as it
4. deal with < aside > in some sane manner
5. add epub_type vocabulary to guide elements where crossover exists and to nav if possible
6. convert nav to toc if toc does not exist
7. convert meta data from new format back to using older format (with opf:scheme, opf:fileas, opf:role) replacing refines with something more sane
8. remove cover manifest property and add in required meta name="cover"
9. there are probably a few other new tags we should convert as well
10 ...

Please add to the list above. Once we agree on the best way to force epub 2, I would also like a similar way to reverse all of this (including reversing the section to div, reversing epub:type to data:epub type, etc ) to force generation of a valid epub 3 from an epub 2 with extras added starting point.

In addition, I am considering to move adding metaguidetext to guidetext from mobi_opf.py to processMobi7() in kindleunpack.py.

That matches what we do for kf8 so that is a good idea.

I am also considering adding in my mobiml2html.py code to convert mobi 7 to something importable into calibre and Sigil, that can be further edited.

I would also like to add a feature that provides the best single output format using the following scheme:

1. if mobi includes SRCS record, then return kindlegensrc.zip is provided return it
2. if mobi has no source, but has azw3, return our unpacked epub from mobi8
3. if mobi has no source, and no kf8 part, use the mobiml2html.py code to return at least parseable proper xhtml version of mobi 7 output.

Please let me know what you think.

CAUTION This update is under development, not intent to end users because the specification is not fixed.

So don't ask for versions of it for a plugin or for your bug reporting JSWolf! ;-)
