Hi DiapDealer and tkeo, and all:

I need some help on what should be considered an epub 3 feature when auto-detect is used?

Here is what I think so far based on what tkeo had previously:

1. "fixed-layout" (EXTH item 122) in the metadata
2. "page-progression-direction" (EXTH item 527) in the metadata
3. "primary-writing-mode" (EXTH item 525) in the metadata and it ends with "rl"
4. RESC itemrefs have "properties"

I would like to add:
5. RESC package version exists and startswith "3"
6. RESC "spine" has "page-progression-direction" (think tkeo used that as well?)
7. RESC metadata uses "refines"
8. RESC metadata uses meta property= attributes

Are there any others we should add? Are there particular version tags or strings in the metadata that only exist/work for epub3 that we could look for when parsing the RESC?

Thanks,

KevinH
