Yep: 1.4.5 Images of Text has exceptions that allow for images of text,
which then (because of 2.5.3 Label in Name) need the accessible name from
the alt text to match the visually presented text. The core purpose of
1.4.5 and 2.5.3, I agree doesn't belong merged in with 1.1.1 and should
stay in the other groups:

   - Text rendering customizability: SC 1.4.4 Resize text, SC 1.4.5 Images
   of Text, SC 1.4.9 Images of Text (No Exception), SC 1.4.8 Visual
   Presentation, SC 1.4.12 Text Spacing

   - SC 2.5.3 Label in Name
   <https://docs.google.com/document/d/1aCRXrtmnSSTso-6S_IO9GQ3AKTB4FYt9k92eT_1PWX4/edit#heading=h.4s1abswqhsz3>
(on
   its own)

I think moving the bit about form labels from 1.1.1 to the label group (SC
2.4.6 Headings and Labels, SC 3.3.2 Labels or Instructions, SC 3.3.5 Help
<https://docs.google.com/document/d/1aCRXrtmnSSTso-6S_IO9GQ3AKTB4FYt9k92eT_1PWX4/edit#heading=h.lze929w6yk2c>)
definitely makes sense!

Thanks,

Shawn
