I can't really comment on the technical accuracy of much of this
document, but other review notes follow.

# Media Accessibility User Requirements

W3C Editor's Draft 21 September 2011

http://www.w3.org/WAI/PF/media-a11y-reqs/

## General comments

- [2] Unnecessarily convoluted use of language, for example
'information presented temporarily' in 2.2. 3.x sections used clearer
language than 2.x.
- [3] It became uncomfortable to read the last part of each 3.x
section, with so much bold text.

## 2.1 Blindness

- [2] 'People who are blind cannot access information if it is
presented only in the visual mode' -> only true if the definition of
blind is having no usable vision, a definition that does not apply to
most people who are registered blind. Following section corrects this
to some extent, but the difference should be explained here.
- [2] 'people who are blind use a screen reader and/or refreshable
braille display' -> braille displays work with screen readers, the
'or' makes no sense. 'people who are blind use a screen reader and
optionally a refreshable braille display'.

## 2.2 Low vision

- [3] 'Glare caused by excessive scattering in the eye can be a
significant problem, especially for very bright content or
surroundings' -> medical information. 'Excessive white space can cause
glare, a significant problem, especially for very bright content or
surroundings'.

## 2.7 Dexterity/mobility impairment

- [1] 'People with physical disabilities such as dexterity' -> I don't
think 'dexterity' counts as a disability. A lack of it, maybe.

## 3.2

- [2] 'synchronisation points with the video' -> struggling to parse
this sentence, should this be 'synchronisation points within the
video'?

## 3.6 Captioning

- [3] 'by associating different colors to different speakers' -> is
the continued use of colour a technique that should be encouraged? If
not refer back to 2.3: Atypical color perception

## 3.7 Enhanced captions/subtitles

- [3] 'This can be realised through inclusion of <a> elements or
buttons into timed text cues' -> <a> but not <button>, be consistent
if referring to HTML elements.
