[media] restructuring of the requirements document

Hi all,

I've had a thorough read of the requirements document for media
accessibility, now at
http://www.w3.org/WAI/PF/HTML/wiki/Media_Accessibility_Requirements .

I am proposing to change the structure to the following:


1. Understanding the needs of sensory impaired users

This will contain everything from the first section up until 1.1.

I propose to create a structure for this by listing the different
types of users, which are currently described each in a different
paragraph:
1.1 Blind
1.2 Low vision
1.3 Atypical color perception
1.4 Deaf / HoH
1.5 Deaf-blind
1.6 Dexterity / Mobility impairment
1.7 Learning disability
1.8 Autism

2. Alternative Content Technologies

This will contain the list of alternative content that is being used
to help the different types of users.
For each of these content technologies, I propose to use 1-2
paragraphs of terse free-text description what they are and how they
are being used, then move on to listing the individual requirements in
a numbered way.
This requires merging some of the sections in 1 and all of the
sections in 2 and extending those from 1 with numbered bulletpoints
that don't yet have them.

I propose the following structure:
2.1 Audio Description
2.2 Extended description
2.3 Clear Audio
2.4 Time Scale Modification
2.5 Captioning
2.6 Extended captioning
2.7 Sign Translation
2.8 Transcripts
2.9 Content Navigation by Content Structure


3. System Requirements

I would like to add this section with requirements for system-wide use
of all of the alternative content technologies described in section 2.
Everything that affects how the alternative content works together and
with the media and other resources will go here.

I'd propose something like the following structure:
3.1 Keyboard Access to interactive controls / menus
3.2 Production practice and resulting requirements
3.3 Requirements on browser settings
3.4 Discovery and activation/deactivation of available alternative
content by the user
3.5 Requirements on the use of the viewport
3.6 Requirements on making properties available to the accessibility interface
3.7 Requirements on the parallel use of alternate content on
potentially multiple devices in parallel
<possibly more>

There is possibly more that has to go here, but I wanted to separate
the requirements on the alternate content (section 2) from the
requirements on the accessibility system that makes all the alternate
content work. I hope this is agreeable.

Cheers,
Silvia.
