[Irl-dean] Color contrast and WCAG 2.2 priority?

[Mark Magennis]

Sorry Gez, I didn't mean to lump you in with the bad guys where you  
obviously don't belong. Appologies for any offence caused.

But I thought (and I still think, having read your post again) that  
you were saying images that can be adequately described by a brief  
statement can also be adequately replaced by a brief text statement.  
My point was that if this statement is provided as an alt attribute,  
then it is not an adequate replacement.

Was I wrong? Were you saying something else, or am I missing  
something about the context in which you said it?
