I still don't see any rationale given for the following three alt exemptions added by your change proposal:

* aria-labelledby attribute present (non-empty only)
* aria-label attribute is present (non-empty only)
* role attribute is present and has a value of "presentation".

The "Rationale" section has a factual description of what these mechanisms are and what they do, but as far as I can tell, no reason is given for why it should be allowed to omit alt when one of these is present. Please either add rationale for these changes or adjust the scope of the Change Proposal to exclude them.


There are also rationale sections relating to a "CAPTCHA Loophole" and a "WebCam Loophole" which do not appear to relate to any actual changes proposed in the Details section. That's not as critical a problem as changes without rationale, but it's something you may wish to address.


Regards,
Maciej
