Re: EPUB 3.3 spec conformity issues

[Per Bothner]

As I understand the situation (not having read the entire discussion carefully):

(1) It is very desirable for texinfo-generated epub to pass epubcheck.
It appears there are only a few minor changes needed to do so,
which increases the priority/desirabilty.

(2) Epubcheck complains about the border="0" attributes in table elements
used in the index. Changing this to border="" or border="1" would satisfy
epubcheck, but this changes the appearance of the index negatively.

(3) I agree that changing the longstanding appearance of the index
would be an unacceptable regression, to many well-estabished manuals and users.

(4) I think the correct fix is to stop using tables for format the index, and 
use
more-appropriate elements along with CSS instead. I think most of us agree.

(5) However, this may be a non-trivial non-local change. It seems unwise to
do this in a hurry or close to a release.

(6) Passing epubcheck is very desirable, but so is not breaking the appearance
of indexes. The latter would be a non-trivial regression. As a general (but 
universal)
rule, not breaking something that currently works takes precedence over fixing
something that has never worked in the past.

(7) Re-writing indexes to use CSS instead of tables should be a high priority -
but most of us are unpaid volunteers. Unless you (Daniel) are willing to do
that (and work non-antagonistically with the texinfo maintainers), you cannot
demand or expect someone else will do the work. It will happen when it happens.
Hopefully soon.
