Matrix of "Authoring Tool's" responsibilities

This is a proposed matrix of which "Web Content Accessibility Guideline" [WCAG] checkpoints are the responsibility of the tool, or the author/user of the tool, or both.

Legend:

Tool =
The tool has the complete responsibility to meet the checkpoint
Both =
Both the Author and the tool share responsibility to meet the checkpoint. The tool alone is not required to implement or it is not feasible to implement all of the function to meet the checkpoint.
Author =
The author has the complete responsibility to meet the checkpoint, however, there may exist techniques that may be implemented by the tool, but are not required to meet the checkpoint.
NA =
Not applicable to apply the [ATAG] checkpoint against that particular [WCAG] checkpoint. For example, it is not applicable to "3.1 Prompt the author for alternative information ..." when the [WCAG] checkpoint is not referring to content, such as in [WCAG] "4.1 Identify changes in natural language ...".

Note: Some of the [ATAG] checkpoints that reference the [WCAG], for example "1.4 Ensure the templates provided ..." and "3.3 Ensure prepackaged content ..." are the responsibility of the Authoring tool developers and should be included in the tool to meet the checkpoint. Another example, "4.2 Assist the author in correcting accessibility problems ..." has a note that "At a minimum, provide context-sensitive help with the accessibility checking required by 4.1". 4.1 is listed in the matrix below.
