Headings at Level 1, SC 1.3

Here's a follow up on the interpretation of 1.3 and 2.4, and whether we
should require Headings etc in level 1 of 1.3 Level 1 SC1

I've been speaking with blind users about how feel about the use of
headings. Headings are a fundamental way that many blind users navigate, not
just a nice extra, more so than in 1999.

Headings are easy to program and do not change the default presentation of a
site. I think we could put them in Level 1.

Ah, now I understand your concern. I agree that there needs to be only a
single file that is the equivalent of the multimedia. If we provide
suitable examples and sufficient techniques, is the following rewording
correct?

<new proposal>

At level 1:
1. For prerecorded multimedia, one of the following is provided:
* captions, or
* a text alternative that conveys the same information as the
multimedia.

2. For prerecorded multimedia, one of the following is provided:
* audio descriptions, or
* a text alternative that conveys the same information as the
multimedia.

At level 2:
1. Captions are provided for multimedia.

2. Audio descriptions of video are provided for prerecorded multimedia.

</new proposal>
