Response from Working Group:
---------------------------------------------
The answer to (a) is "yes". If a Web page does not contain content
that uses analogue input, then if it meets 2.1.1, it will also meet
2.1.3.

The answer to (b) is "no". The Level A success criterion must be
satisfied to conform at Level A. That it also satisfies a Level AAA
success criterion is immaterial for Level A conformance.

Note, of course, that your questions were limited to Web pages that do
not contain analogue input. For pages which do contain analogue input,
satisfying 2.1.1 does not also satisfy 2.1.3.

Your proposed restatement of 2.1.1 is equivalent to the current
success criterion 2.1.1. If 2.1.3 were dropped, then Web pages that
contain analogue input would conform at Level AAA. The purpose of
2.1.3 is to ensure that all content is keyboard operable.

At level A, it is permissible to have content that requires
time-dependant analog input without providing a keyboard accessible
alternative. This is not permissible at Level AAA because of success
criterion 2.1.3.
