aloha, y'all!

at thursday's telecon, gregg asked me to post the User Agent Accessibility
Guidelines' content-type and output modalities to the GL list...  i asked
permission to wait until ian published a new draft, and on bastille day, 14
july 2001, the latest working draft of UAAG 1.0 was released...  it lives
at:
<http://www.w3.org/WAI/UA/WD-UAAG10-20010714/uaag10.html>

the pertinent bits follows:

3.5 Content type labels
<http://www.w3.org/WAI/UA/WD-UAAG10-20010714/uaag10.html#content-type-labels
>

   Each content type label defines a set of requirements related to
   support for images, video, animations generally, visually displayed
   text (in color), and synthesized speech.

   VisualText
          This content type label refers to all of the requirements
          related to the visual rendering of text for the following
          checkpoints: 3.3, 4.1, and 4.2. To conform, the user agent must
          support visually rendered text.

   ColorText
          This content type label refers to all of the requirements
          related to text foreground and background color for the
          following checkpoint: 10.4. To conform, the user agent must
          support more than one text foreground color and more than one
          text background color.

   Image
          This content type label refers to all of the requirements
          related to images (excluding animated images) for the following
          checkpoints: 3.1, and 3.7. To conform, the user agent must
          implement at least one image format. The image requirements
          apply to content that is recognized as distinct and that,
          according to the encoding format, may be rendered as a coherent
          unit.

   Animation
          This content type label refers to all of the requirements
          related to animations (including video and animated images) for
          the following checkpoints: 3.2, 4.4, 4.5, 4.7, and 4.8. To
          conform, the user agent must implement at least one animation
          format. The animation requirements apply to animation content
          that is recognized as distinct and that, according to the
          encoding format, may be rendered as a coherent unit.

   Video
          This content type label refers to all of the requirements
          related to video for the following checkpoints: 2.5, 2.6, and
          3.2. To conform, the user agent must implement at least one
          video format. The video requirements apply to video content
          that is recognized as distinct and that, according to the
          encoding format, may be rendered as a coherent unit.

   Audio
          This content type label refers to all of the requirements
          related to audio for the following checkpoints: 2.5, 2.6, 3.2,
          4.4, 4.5, 4.7, 4.8, 4.9, 4.10, and 4.11 To conform, the user
          agent must implement at least one audio format. The audio
          requirements apply to audio content that is recognized as
          distinct and that, according to the encoding format, may be
          rendered as a coherent unit.

   Speech
          This content type label refers to all of the requirements
          related to synthesized speech for the following checkpoints:
          4.12, 4.13, 4.14, 4.15, and 4.16. To conform, the user agent
          must support synthesized speech.

   Note: Some of the labels above require implementation of at least one
   format (e.g., for images). This document does not require
   implementation of specific formats, (e.g., PNG [PNG] versus SVG [SVG]
   for images). However, please see the requirements of checkpoint 8.2.

3.6 Input modality labels
<http://www.w3.org/WAI/UA/WD-UAAG10-20010714/uaag10.html#input-modality-labe
ls>

   Each input modality label defines a set of requirements related to
   support for pointing device and voice input. Input device requirements
   in this document are either stated generically (e.g., "input
   configuration" requirements) or as keyboard-specific requirements
   (e.g., "keyboard API").

   Pointer
          This input modality label refers to all of the input device
          requirements of this document, applied to pointing device
          input. For keyboard-specific requirements, substitute "pointing
          device input" for "keyboard." The set of pointing device input
          requirements does not include the requirements of checkpoint
          11.4.

   Voice
          This input modality label refers to all of the input device
          requirements of this document, applied to voice input. For
          keyboard-specific requirements, substitute "voice input" for
          "keyboard." The set of voice input requirements does not
          include the requirements of checkpoint 11.4.

   Note: Developers are encouraged to design user agents that are at
   least partially operable through all three input modalities.

3.7 Selection label
<http://www.w3.org/WAI/UA/WD-UAAG10-20010714/uaag10.html#selection-label>

   This document does not require the user agent to implement a selection
   mechanism in order to conform. However, if the user agent does
   implement a selection mechanism, in order to conform it must satisfy
   the relevant portions of the following checkpoints:

   6.5
<http://www.w3.org/WAI/UA/WD-UAAG10-20010714/uaag10.html#tech-api-alert>
   7.1
<http://www.w3.org/WAI/UA/WD-UAAG10-20010714/uaag10.html#tech-selection-focu
s-conventions>
   9.4
<http://www.w3.org/WAI/UA/WD-UAAG10-20010714/uaag10.html#tech-tracking-previ
ous-por>
   10.2
<http://www.w3.org/WAI/UA/WD-UAAG10-20010714/uaag10.html#tech-selection-focu
s-highlight>
   10.3
<http://www.w3.org/WAI/UA/WD-UAAG10-20010714/uaag10.html#tech-default-highli
ght>
   and 5.4
<http://www.w3.org/WAI/UA/WD-UAAG10-20010714/uaag10.html#tech-track-selectio
n-focus>

   The Selection label refers to the selection requirements of these
   checkpoints.

   If a user agent does not implement a selection mechanism, then a
   well-formed claim must say so.

   Note: This document does require implementation of both content focus
   and user interface focus; see checkpoint 9.1

<http://www.w3.org/WAI/UA/WD-UAAG10-20010714/uaag10.html#tech-nav-content-fo
cus>
   and checkpoint 9.2.
