If you’ve ever taken a read of the EPUB 3 Content Documents spec, you’ve undoubtedly seen the warnings about HTML5 features being experimental, and to use them with caution. Caveat emptor and all that…
Did you ever skip on over to the HTML 5.0 spec and have a look at what features those were? Did you use them with caution? (Everyone follows specs to the letter of the law, right?)
If not, as the 5.0 revision winds down you might have missed the various features that have recently been pushed out. If you liked the
summary elements, for example, you’re waiting for HTML 5.1 now for official status.
So where does that leave the world of EPUB 3?
