We have changed the definitions to be technically accurate but easier
to understand. \

> EOWG reply on Comment 19 distinction between blinking and flashing still isn't clear:
> 1. EOWG still feels like the distinction between blinking and flashing in WCAG 2.0 is difficult to ascertain, the definitions did little to help, and the specific technical language turned off some. While we realize you need precision in the technical specification, we encourage you to work on making these more approachable and easier to understand.
> Please consider:
> - Include plain language description and/or examples of blinking, flashing, and the distinction between them.
> - For the flash definition, start with a more easy to understand definition and put the technical specifics after that.
> - For the blink definition, provide a self-contained definition, rather than defining it only in relation to flash.
> - Put the simple language in the definitions themselves as possible, or at the least in a note with the definition in /TR/WCAG20 doc.
> - For the both definitions, link to more explanation and/or examples of each and of the distinction, e.g., something like the new Note in Understanding (Note: In some cases, what we refer to as "blinking" and what we refer to as "flashing" may overlap slightly. We are using different terms for the two because...)
> Some background:
> - "Then the wording used for the flash definition is weird... "a pair of opposing changes in relative luminance of 10% or more where the relative luminance of the darker image is below 0.80"
> I really have no idea what that means." - http://lists.w3.org/Archives/Public/w3c-wai-eo/2007OctDec/0083.html
> - http://www.w3.org/2007/11/16-eo-minutes#comment19
> 2. We assume that the word "flash" should be linked to its definition in the text of 2.3.1 and 2.3.2.
> 3. (Also we noted a little "typo" in 2.3.1 Three Flashes or Below Threshold: Web pages do not... where the word "do" is included with "Web page" in the link.)
