Hi all,

On the Jan 31 call, Jim took this action:
ACTION-798: Review 'recognized' in SC to make a top level statement similar to device independence at the beginning of the document - perhaps an applicability note and something in a conformance claim..( https://www.w3.org/WAI/UA/tracker/actions/798)

And Eric's excellent review also highlights the repetition of "recognized".

I'd like to suggest the following "ported" ATAG2 wording along with a few other relevant high level conditions:
 
1. Unrecognizable content: Any success criteria that refer to semantic features of web content  (e.g., text alternatives to non-text content, headings, keyboard commands, time limits, etc.) will only apply when those features are implemented according to standard semantics for the web content technology. When those features are implemented via other means (e.g., custom scripting), the content features are not considered recognizable and the success criteria do not apply.

2. User agent  systems: As per the UAAG 2.0 definition of user agent, several software tools (identified in any conformance claim) can be used in conjunction to meet the requirements. For example, a base user agent could make use of plug-in to provide certain functionality and a web-based user agent may rely on base user agent features (e.g., keyboard navigation, find functions, etc.). 

3. Developer control: The success criteria only apply to the user agent user interface as it is provided by the developer. They do not apply to any subsequent modifications by parties other than the developer (e.g., user modifications of default settings, third-party plug-ins). 

Cheers,
Jan
