Re: ACTION-846 and ACTION-847 concerning platform limitations in Conformance section

+1
I like the new wording, it leaves little doubt as to what is an exception.

to make it easier to read, here is the proposal with no extra markup

Proposed new wording for paragraphs 7 and 9 7. Platform Limitations: If the
platform does not support capabilities necessary for some UAAG 2.0 success
criteria, list the success criteria and the features. For these listed
technologies, the declarations section can claim that the success criteria
do not apply due to platform limitations.

Note: For the purpose of paragraphs 7 and 9, platform includes only the
hardware, operating system, or cross-platform operating environment, as
these generally cannot be replaced without substantially changing the
target market. For example, if the user agent runs on an operating system
that does not provide platform accessibility services, a conformance claim
for this configuration can list the result for each related success
criterion as "Not applicable due to platform limitations", and describe the
specific platform limitation. However, if the user agent designers choose
to use a widget library that does not support the platform accessibility
services, they could not claim an exemption based on that decision.

9. Declarations: For each success criterion, provide a declaration of
either:
    a. whether or not the success criterion has been satisfied; or
    b. declaration that the success criterion is not applicable and a
rationale for why not from the following choices, along with appropriate
details:
        1.  Not applicable due constraints of the platform, as per
Paragraph 7 above (e.g. color handling when the browser is designed for a
monochrome device, video handling in a purely audio browser, or
interprocess communication on an operating system that does not support
multitasking)
        2. Not applicable due to a constrained input set (e.g. audio
requirements when a help system that only displays text content from HTML
files included with the product)
        3. Not applicable due to limited output modalities (e.g. video
handling in a browser that only does audio output, even though the platform
may support video)

For comparison, here is the existing wording:
7. Platform Limitations: If the platform (hardware or operating system)
does not support a capability necessary for a given UAAG 2.0 success
criterion, list the success criterion and the feature (e.g. a mobile
operating system does not support platform accessibility services,
therefore the user agent cannot meet success criterion 4.1.2). For these
listed technologies, the user agent can claim that the success criteria do
not apply.

9. Declarations: For each success criterion, provide a declaration of either

    a. whether or not the success criterion has been satisfied; or
    b. declaration that the success criterion is not applicable and a
rationale for why not
