I have been reviewing the implementation information forms that have
been submitted for WCAG 2, and I have concerns that we may not have
"positive examples" for the following success criteria. Positive
examples are content that meets the success criteria, but not simply
by absence of applicable content.

1.2.1 (Audio-only and Video-only (Prerecorded))
  - we have implementations for audio-video, but need examples of
audio-only and/or video-only

1.2.4 (Captions (Live))
1.2.9 (Live Audio-only)
   - we need implementations that contain live time-base media

1.3.3 (Size, Shape, Location)
  - we need implementations that refer to controls by these
properties, but not exclusively

1.4.2 (Audio Turnoff)
1.4.7 (Low or No Background Audio)
   - We need sites with audio content - some that plays automatically,
and some that contains speech

2.2.1 [Timing Adjustable]
   - We need content that contains time limits

2.2.2 [Pause, Stop, Hide]
  - We need content that contains moving, blinking, or auto-updating content

2.2.4 (Interruptions)
  - We need content that generates interruptions.

2.2.5 (Re-authenticating)
  - We need implementations that have sessions that expire.

 2.3.1 (Three Flashes or Below Threshold)
 2.3.2 (Three Flashes)
  - We need implementations that flash.

3.3.3 [Error Suggestion]
   - We need implementations that suggest corrections.

3.3.4 [Error Prevention (Legal, Financial, Data)]
  - We need implementations that cause legal commitments or financial
transactions, that modify or delete user-controllable data, or that
submit user test responses.

3.3.5 [Help]
  - We need implementations that provide context-sensitive help.

3.3.6 [Error Prevention (All)]
  - We need web pages that submit information

I was not able to tell whether or not we have examples for the
following success criteria, so we should look for these
implementations, as well:

1.4.1 (Use of Color)
  - We need content that uses color to convey information

3.1.3 [Unusual Words]
  - We need implementations that provides definitions of works used in
usual ways.

3.1.4 [Abbreviations]
   - We need implementations that provides the meaning of abbreviations

3.1.5 [Reading Level]
    - We need implementations that uses text below lower secondary
education level or that provides supplementary content.

3.1.6 [Pronunciation]
    - We need implementations that provide pronunciation information.

 3.2.4 [Consistent Identification]
   - We need implementations that contain components that provide the
same functionality on different web pages.
