Summary of Issue: clarification of the term \'perceivable\' 
Comment (Including rationale for any proposed change):


\"users must be able to perceive the information being presented (it can\'t be invisible to all of their senses)\"   



This statement for Principle 1 still relies on the term \'perceivable\', and does not fully clarify the state of becoming aware of the availability of the information. 



Proposed Change:
\"users must become aware of the availability of the information being presented through the senses (it can\'t be invisible to all of their senses)\"
