Hi Alistair,

as long as the SC is met, it is not important which technique is used. It's not throwing their techniques choice out of the window because if the SC is met everything is fine. A problem is the following: testing against sufficient techniques. In this case the developer has no chance for own techniques which is not the idea of WCAG2. I think an evaluator will know if an SC is met regardless which technique is used. Therefore 1e leads to the situation that people look more for techniques and less for the SCs. Making 1e as required will close the door to new techniques and I fear could lead to the situation that evaluators are telling people to choose their faved techniques. Therefore 1e should be deleted.

Regards

Kerstin
