RE: Do icons fall under - 1.3.3 question for shapes/icons alone that are used everywhere now but were not back in 2008

Patrick,

Yes, you are correct, it is a perception or Sensory Characteristic.

My other challenge is knowing “for sure” what it is 1.3.3 covers and being able to communicate it to developers and others who are asking.

Thanks.

I believe Alan's point is not necessarily about people who cannot 
perceive the images at all and would therefore get text alternative (as 
per 1.1.1), but rather people who can visually perceive the images/icons 
but won't necessarily understand them without a visible additional label 
text - while users falling under the cognitive disability side would be 
most affected (presumably?), this is likely an issue that can apply to 
all sighted users too ("mystery-meat navigation" etc).
