As a preamble to this discussion, I think we need to define more precisely ("measure"?) what an "impact" would be (for example, impact to whom/what and what specifically are the consequences of said impact)?

Thanks Tim

Dear all,

I would very much like to discuss section 5.5 about Error Margin.

If one out of 1 million images on a website fails the alt-attribute this could mean that the complete websites scores a fail even if the "impact" would be very low. How do we define an error margin to cover these non-structural errors that have a low impact. This is already partly covered inside WCAG 2.0. But input and discussion would be great.

Please share your thoughts.
Kindest regards,

Eric
