RE: pre-considerations for Part A Level A SC of ATAG

Here are some proposals to attempt to meet Tim's concerns:

1. "[Do] All user interfaces [need to meet A.1.1 and A.1.2] or just one"

PROPOSAL: Combine and reword Part A Conformance applicability Notes 1 and 5 to make the existing exceptions more clear:

Conformance applicability note: 1. Scope of "authoring tool user interface": The Part A success criteria apply generally to all aspects of the authoring tool user interface including editing-views, other features that support editing (e.g. menus, button bars, status bars, user preferences, documentation, etc.) and features added to meet ATAG 2.0 success criteria (e.g., search functions, checkers, etc.). The only exceptions are the following: 
- Features for Editing Other Technologies: Authoring tools conform to ATAG 2.0 with respect to one or more *web content technologies produced*. Part A does not only apply to user interface features that are involved solely with production of other web content technologies.
- Previews: Part A (except the relevant success criteria in Guideline A.3.7) does not apply to previews because all authors, including those with disabilities, benefit when preview features accurately reflect the functionality of user agents that are actually in use by end users.
- Redundant Non-Interfering Features: Features can be present that do not meet the success criteria in Part A only if (a) the functionality of the feature is provided elsewhere by a feature that does meet the success criteria; and (b) the feature also does not interfere with the ability of authors to access the rest of the authoring tool user interface (e.g., by blocking audio control, trapping keyboard focus, etc.).

ED.: I don't think this is a substantive change. It reflects a conformance condition in WCAG2 - but since we no longer require "conformance" (we now talk about meeting WCAG 2.0 SCs) to WCAG it's worth saying.

2. Defn of time-based media that also pulls together the existing audio and video defns:

time-based media:
Content that is rendered over time to produce a changing sensory experience. Time-based media may include one or more of the following modalities. 
- auditory time-based media (audio): The technology of sound reproduction. Audio can be created synthetically (including speech synthesis), recorded from real-world sounds, or both.
- visual time-based media (video): The technology of moving pictures or images. Video can be made up of animated or photographic images, or both.
- tactile time-based media (tactile animation): The technology of moving tactile representations. Tactile animation is supported by haptic devices and refreshable Braille displays.
Note: Time-based media may include interactive elements.

ED.: Not a substantive change to any of the SCs.

3. Additional text for Relationship to WCAG section:

"The ATAG 2.0 Glossary shares many terms with the WCAG 2.0 Glossary. In general, the definitions are fully harmonized. In some cases, the definitions have been edited slightly to useful apply to the context of authoring tools, with no substantial re-definition intended."

ED.: Not a substantive change.

4. Tim identified statements such as "authors can X" (and I'm assuming the related "authors have the option to X") as problematic for testing because they imply testing the author not the tool.

Do other people share the concern? 

If so, a solution would be to reword these as: "the authoring tool allows authors to X". It would affect the following:

A.2.1.2 Alternatives for Rendered Time-Based Media:
A.3.2.2 Timing Adjustable
A.3.2.3 Static Pointer Targets
A.3.6.4 Multiple Sets
A.3.7.2 Preview (Enhanced)
A.4.1.3 Content Changes Reversible (Enhanced)
B.1.1.1 Content Auto-Generation After Authoring Sessions (WCAG)
B.1.1.2 Content Auto-Generation During Authoring Sessions (WCAG)
B.1.2.1 Restructuring and Recoding Transformations (WCAG)
B.2.2.3 Technology Decision Support
B.2.3.1 Alternative Content is Editable (WCAG)
B.2.3.2 Conditions on Automated Suggestions
B.2.4.3 Author-Create Templates
B.3.1.4 Status Report
B.4.1.2 Option to Reactivate Features
B.4.1.3 Feature Deactivation Warning

ED.: I don't think this is a substantive change since it was already implied.
