Item Number: Success Criterion 1.4.3
Part of Item: 
Comment Type: TE
Comment (Including rationale for any proposed change):
These comments also apply to 1.4.1:



1.  Is it realistic to expect authors to do the math to figure out the luminosity contrast ratio?

2.  Why isn\'t MathML used to represent the equations?  

3.  If the only difference between 1.4.1 and 1.4.3 is the ratio (5:1 vs 10:1), then drop one ratio and therefore one needless requirement.    

Proposed Change:
1.  Use MathML to represent the equations.

2.  Eliminate either 1.4.1 or 1.4.3, preferably the latter.   

3.  Reconsider the expectation that authors will determine contrast through the use of the luminosity contrast ratio.  Did anyone in the working group poll authors to see if this is realistic?
